Its hard enough as it is with the right colors: Rubik's Cube Revenge

(tags Rubik's Cube, failure)

This is my Rubik's Cube Revenge, which is a 4x4x4 cube. I've only kept it around for decoration since I have no idea how to solve it. I can't remember when I bought it, but its been sitting near my window for years.

Now that I'm feeling the Rubik's Cube fever again, I tried solving it. Unfortunately the green-orange(?)-red corner had a peeling sticker that fully separated last weekend. The other stickers are pristine though. What a waste. I guess I'll order some stickers some time. This store seems to be promising, but perhaps there is some local (Japan) store.

edit: Um, its a Revenge, not a Professor (5x5x5). Oh yeah, the official Rubik's Cube licensee, Mega House, provides support with services such as official sticker replacement.
