The community of glass artists I'm in has sold tons on facebook over the last few years. FB has always let you sell in Groups, and unlike many online venues, has zero problem with art glass pipes. It was the #1 place to sell online 2011-2013, then the community switched to Instagram. Instagram has since been the #1 place where people hold auctions and sell glass since then, and that's from $10 pendants to $500 tubes and up to $10, 20, 30k pieces.

So, to sell on FB, you say hey, i have this piece for $300, here's pics, I take paypal.

FB works with a handful of ecommerce platforms to enable this natively as well. https://www.bigcommerce.com/facebook/
