Royal Glam Aluminum Wrist Rest

Hope this is available again soon, I need another 60%. Anyone know if it's available anywhere else?

Received mine last week, but the left rubber feet had weird streaks on them and had a small hole (didn't punch through it though). It looks like it was tempered with or put under pressure from some careless machining. The wrist rest itself, though, was in stellar condition.

I finally received the wrist rest and the machining is clean. But there some streak that stained from miss handling or etc leaving darker shade streaks. Not exactly sure how to remove streaks. I've tried wiping with WD-40 and 90% Isopropyl Alcohol and it doesn't seem to do anything. Any recommendation to remove these dark streaks?
