So i got a buddy who is selling a bowl he said it was used once or twice. I know I Can clean that but here is the description of it It is about 3-4 Inches, Glass and it is color changing. I'm waiting for some pictures from the guy. But what should I be looking for? He is asking for 10 bucks on it and I Was looking to spend 20 so this is less than what I Wanted and 10 for some other stuff So what should I look for and btw this is my first post!!!
