I have these two old Carey Magic Inch briars with some slightly questionable stems... These are fairly old pipes, I think, yet they have very shiny stems with a few bite marks and scuffing. I'm nearly positive it's not vulcanite, or it probably would have oxidized by now. So I'm thinking some sort of acrylic, but it is relatively bendy (couldn't break this thing if you tried) and is very soft and comfortable. Thoughts? I would really like to know what it is because i would but a new pipe with this type stem in a heartbeat.
