I used to constantly have to pause in game readjust my grip on aim maps and I no longer have to. I used to focus way to much on aiming streams instead of tapping them properly because my grip before korelax was so uncomfy, but no more. Thank you korelax and thank you btmc (Ed) cause without your video I would have no idea this existed and he stuck using the foam I use to pad my keyboards to make them sound better as a moldable grip

Worth the couple of bucks.

They make the pen thicker as I was hoping for, and they give a pretty good grip. The only problem I've had is they react to sweat pretty poorly in heat, but in colder temperatures, work as intended. 5 stars overall, would recommend to osu players and artists alike.

Fits well, even over my original grip. Great texture, easy to apply. Works well as a normal grip or even an over-grip. Can't get much better.

An amazing all-rounded pen grip with an even better customer service.

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.
