Planet Walls were available in the BETA days. This item costed 150 gems. This is a valuable BETA. These only came in 1 form, and are now hard to get. Many people want these, if they are a BETA fan. Lots of Jammers want them because of the rarity. These are worth Blue Shag Carpet, Yellow Sweets, Red Brick Walls, Rare Short Spike Collar (certain colours), or another similar good BETA. It's hard to find someone who has these, and certain people will want it badly. If you want to keep this item, you can keep it, since I don't think wallpapers and flooring are coming back.
