The grip is great. It's only about 1mm thick, so putting it on the pen (wacom CTL-4/672) barely changed the width, and is much nicer compared to something like a tennis overgrip. The diamond texture on the outer surface of the grip ensures very little to no slipping, and the inner horizontal circle texture also keeps the grip from moving on the pen itself. It seems like it'll work fine put on either normally or inverted, so that will be up to preference. Do be sure to watch the instructional videos posted by Korilak at the top of the website to learn how to put on and adjust the grip properly. The grip does help a lot with keeping the hand steady and I find myself setting better plays because of it. The grip does go straight over the pen buttons, and I'm not sure it does much to help prevent button presses, but your results will vary depending on how you hold the pen. I will say that it makes the buttons far less noticeable, which is very nice. There is a ridge on one end of the Blueberry that helps with rolling the grip up for removal/adjustments, and it will be helpful for keeping your fingers off the tip of the pen if you hold it very close. For me, it works well as a position marker to keep my grip at a consistent position between different times holding the pen.

The first Blueberry I received from Korelax may have been defective, and while I was adjusting its position on the pen, the ridged end was torn with only a pull. My nails may have been a bit sharper than usual that day. But anyways, I sent off an email to Korelax sales and was given some instructions on how to mitigate the damage while they sent me replacements free of charge. Huge thank you for being very communicative and receptive to feedback that I gave for multiple points on the grip.

As another person mentioned, there are two seams running down the length of the grip on opposing sides of the grip, and I have been told that they are looking into ways of getting rid of it.

Overall great grip, great company, 10/10 would buy again.

Brilliant grip. I am able to achieve greater aim control while my pen maintains a sleek profile. I was sort of expecting to have some sort of issue with the material irritating my fingers due to the friction on the rubber, but I was proven so incredibly wrong. Have been using this for about a month now without issue and have already recommended it to one of my friends who has been using it this past week.

HUGE upgrade from my previous setup, which was first a paper towel taped to my pen, then electrical tape, then tennis racket tape, but none of these granted me the same level of control and comfort as the Blueberry.

10/10 highly recommend

if you don’t buy this you are brain dead mandem

Used this with the stock pen from the Wacom CTL 472 to play osu! and it fits perfectly for me. It's been super comfy to use, and since using it, I haven't had any issues with slipping or thoughts of having to readjust grip.

I went from struggling to grip my pen when doing spaced jump patterns on osu! To doing them very comfortably without any worry of my pen sliding what so ever. There were times where I’d completely drop my pen mid play but this solved the issue!!

i like the included pen tool to help you roll it up and roll it out onto the pen, it made putting on the grip much easier than i was expecting (i see why its called the blueberry now :D) only gripe is there are some mini ridges on opposite sides of the grip (i assume as a result of imperfections in the manufacturing process or something) which are not very obstructive but i can still notice them somewhat. still a good grip overall

I had an issue with my first shipment of grips, but their customer service was amazing. They quickly sent a replacement set, the grips themselves are high-quality and super comfortable especially for osu!, easily reccomend to anyone who needs some serious grips that last for a long time.

I use the thick and it a great quality, I though first I would use the thin one, but its to thin for my hands. Because is very thin, IT CAN BREAK QUICKLY (on my unit is already a small break, at the middle par) but overall its a great quality too!! not so great like from the thick one, but its great.
If u buy the bundle, I can NOT recommend to not switch between both to much, but I can recommend buying something from here!!
For the thick one I can tell you, you can squeeze it a lot and you still have a perfect grip and you won't slip it you get your new grip style with it.

I got the Aero Thin grip because I always slowly slide down my Wacom pen when I use it normally for digital art. I've previously used rubber bands, and they don't offer anywhere near as much consistency and ergonomics as this grip does.

Highly recommend putting one of these on your digital pens. It's improved my drawing speed because I don't feel the need to adjust my fingers often. It's just thick enough for softening my pen for extended periods of use, whilst thin enough to retain the natural shape of a pen. The openings for the buttons are great for keeping my pen buttons accessible for shortcuts!

I always use this on my pen now. It's aesthetic, has phenomenal grip, and is very easy to take off/put on for when I clean it with water. Highly recommend!

I wanted to try both thick and thin I ended up liking thick more but overall good grip better than grip tape and easier to put on and take off.

As an average 5 digit osu! aim player, one of the common issues I run into is my pen grip failing on me when I'm trying to do cross screen jumps even at a lower bpm. this issue is completely fixed with the korelax pen grip. It may take some time to get used to the adjustment however the pay off is insane, with this grip you're able to completely trust your aiming hand and let your fingers take over. tldr easy to apply, easy to use, works perfectly as intended.

Korelax has single-handedly erased any grip issues that I previously had. I’m a longtime player since 2015 and throughout the years I’ve suffered from fingers slipping down the pen during gameplay. Grip tape barely cuts it, and it deteriorates quickly. I’ve tested the Clutch and Clutch No Tail and can confidently say I will be keeping the Clutch on my pen for permanent use. I’ve always dreamed of having something protruding out the pen just for something more to grab. On top of this, the silicone material that it uses is very grippy. This grip allows me to flick my aim for full screen corner jumps with a locked in grip that does not move, whereas before I would be sliding all over the place no matter what I did. It’s genuinely unlocked more maps to be playable for me.

To compare the Tail and Non Tail versions really depends on the type of grip that you have. I’ve preferred the tail over not having it as it gave my middle finger somewhere to sit and not move. It did take a small adjustment period as I usually have it further down the pen, but after just an hour I got used to it. The only other aspect I will mention to consider is because the grip is so good, I found myself hard snapping initially. I made a conscious effort to not do this, and then had normal looking aim in no time at all.

I would recommend the Clutch Tail to anyone with a suitable or near suitable grip style. I would also not shy away from slightly adapting your finger positions to better suit the grip as this will allow you to consistently grab the pen in the exactly same way every play session. I think the No Tail variant would only be useful for a small number of grips where the stopper would get in the way.

As someone who has struggled with aim and pen grip in the past, this product is honestly a game changer and is legitimately a tool to make you more consistent and potentially a better player. I can see this product being the gold standard for peripherals, similar to what Wooting has done in the keyboard space.

As someone who spends hours using the tablet for studies or playing rhythms games like osu, I've struggled with discomfort and finger pain due to the way I grip my tablet pen (potentially due to being left handed using a right hand grip). After trying several solutions, I came across the Korelax Aero Tablet Pen Grip, which has significantly improved my experience.

The Korelax Aero grip has been a game-changer in terms of comfort. The design fits perfectly around my pen, providing a much more comfortable hold. The soft, ergonomic material reduces the strain on my fingers, particularly in the areas where I usually feel pain after extended use. The grip allows me to maintain better control without feeling the discomfort I used to experience.

While the Korelax Aero excels in comfort, it falls short in one crucial area—customization for users who modify their pens. Like many osu players, I’ve removed the button on my pen for better game play. Unfortunately, the grip’s design accommodates pens with buttons, leaving a noticeable hole when the button is removed. This creates a slightly awkward feeling and detracts from the otherwise seamless experience.

I would love to see Korelax introduce an option to fill in this gap or offer grips designed specifically for pens without buttons. This small change would cater to a broader audience and enhance the overall user experience.

it grippy good

I've used it for 2 days now, for very long osu sessions and the grip feels nice the whole time. When it gets wet from sweat it dries really easily and a couple wipes from a towel or something also dries it completely.

The Korelax Ridge is awesome for osu! I personally use the Ridge Classic - Thin. It's super comfy and helps me aim better, without my hand getting tired. The little ridge on the end is perfect for pinching and my thumb and index never slip out into each other. The grip stays put on my pen, even during crazy fast songs. It's durable and looks cool too. Definitely a must have for any osu! player!
