PS405 Mouse Cover 3 3/4" x 7" 500/Box

The plastic is too thick and rolling the scroller is impossible. Also the size is too large, makes the mouse slide out. Don’t recommend them

The mouse doesn't work properly with the cover in place.

These covers worked fine when tested with various optical mice. The only issue I had was using the scroll wheel. The bag/cover restricts upward movement of the wheel. These still work well enough for my needs.
