So, I have amassed a much too large collection of glass pieces while in college, and my girlfriend has made it abundantly clear that the party is over (not that we are going to quite smoking, but that the collection is no longer going to be appreciated). Anyway, my roors, vapes and sentimental pieces are sticking around, but all my other pieces have to go. They are all super clean (just used Grunge Off), but they are used, which concerns me for selling them. Can I sell on craigslist if they are 100% clean? If not, where can I? Thanks guys, and if any of you are guys are interested in a local glass blower version of a Helix Pipe with 14mm ground joint for $60 pm me for pics. I also have a bamboo steam roller, small frosted glass green steam roller with rasta stripe around the front, and a small mushroom shaped pipe that I am selling for $10 a piece.
