Other Buying Accessories on Ebay?

It depends but I wouldn’t recommend it unless it’s from a trusted seller that has good quality glass because I bought a pipe a while back and it’s made out of cheap glass, came chipped, and was hard to smoke out of so I had to make the hole in the bowl bigger and part of the mouth piece also broke off with ease so I don’t even use it. On another note I bought a bong on eBay from a good/trusted seller and it was one of my favorite bongs but I broke the mouth piece off it the other day which sucks. It can be fixed just haven’t got to it yet.
