Optical Super Slim Mouse is very slim, at 10mm thickness and it’s as large as your hand.
The designer Lukasz Natkaniec is making this optical mouse as simple as he can, so you can only see a glowing light in the middle of two buttons’ strait without any other gimmick added. The click buttons also flat enough but it has some level of height or ergonomic curve in the middle to support your palm.
Looks very cool. It makes those who use this mouse feel like they are not holding a mouse at all.
