Big RockEngineering – X-1 Aluminum Stick-On Guitar Pick PowerGrips (2 Pack) – Includes (6) X-1 P-82 Multi-Function Adhesive Strips – For Improved Control and Easier Play

It's very expensive for what you get, and it still does not work well for me. I am missing my right index finger, so it makes it very difficult to hang onto a pick. I am using tethered picks. They are the only ones that work for me.

This is kind of a nice idea, just not quite the solution I'm looking for. If I made something similar out of wood, I could customize the shape and add more thickness.

I play bass and my pick is constantly sliding around when I'm playing fast. So I have to hold the pick tighter, which makes my whole arm tight. I was searching around for a solution, and stumbled onto these X-1 grips. I got mine yesterday and it's amazing! I just use one of the two on my thumb-side and it's perfect. I can completely relax my hand now, and the pick doesn't slide around. Also, I can use the same pick I always use. Honestly, I played better the first time I tried it. I'm super happy and am definitely gonna buy more.
