Sorry about the dust
Black plastic really just loves showing off the dust
So I realized a while ago I had a tendency to flop my pen down and let the hard plastic bang around. This happens a lot when flipping over to use the eraser side, it would also occasionally hit the tablet surface. After A while I noticed parts started to feel slightly loose. To fix this I put a rubber band over where the logo was and the damage hasn't increased at all and it has a tad more traction when placing it on it's side so it's less likely to roll away.
Just thought I would throw this tip out there
It stops the hard plastic from hitting the writing surface (it also lifts it enough that the button part doesn't hit either)
Less likely to roll off
Nice bumper for the pen
If you care about the "wacom" screen printed logo rubbing off it protects that too
