Kulture no longer stocks Sheldon Black water pipes due to unforeseen circumstances. We now carry our own brand of water pipes which cover the basics, like straights, beakers, dome percs, tree percs, UFO percs and inlines. Check out Kulture water pipes in our online store. If your are looking for scientific pipes with innovative percolation may we suggest Toro water pipes, 4.0 Glass water pipes, Mobius Glassworks water pipes, and Termini Tubes. All are very comparable in terms of quality to Sheldon Black water pipes. Just in from Sheldon Black Smokeware is the new double bubbler and Mike Fro worked diffuser and martini slide sets. Just in time to use the money that Grandma gave you for Xmas too! Even after seeing around 20 photos of the double bubbler or "Doubbler" as it was listed on the invoice; I still couldn't wrap my head around it. It has two six arm tree perc and can be used as a single chamber or a double chamber. This is because of a clever little addition. It looks like a GonG snorkel carb, but when it's removed, the smoke bypasses the top chamber and is only filtered by the bottom tree perc. It also comes with a removable mouth piece, which comes in handy for storage. If you break it, it's an easy replacement as well. There's only one available right now. We wanted to check it out first before ordering a bunch. What we did order a bunch of were the Mike Fro diffy and martini sets. Unfortunately we were only sent two. They're cut for beakers and have pierced holes. They look as you would expect from Mike and Sheldon. Clean lines from Mike and a classy look from Sheldon.
