Silicone grip caps for game controllers. Set of 2. By attaching them to the analog sticks, you can prevent slipping and get a more comfortable grip. (This is based on my personal experience.) They seem to be compatible with the following controllers: ◆NINTENDO Switch, Wii-U… ◆SONY PS5, 4, 3… ◆Microsoft Xbox360, One, Series X / S… I tried them on my AYANEO Pocket EVO, which I own, and they fit without any problems, so they may also fit controllers with analog sticks of a similar size. (However, I cannot guarantee this...) If anyone is interested, please let me know. Thank you very much. m(_ _)m
