🧪 10-Pack of Pyrex Glass Tubes - 12mm OD, 2mm Thick Wall Tubing for Hydraulics, Pneumatics & Plumbing Review

All 10 come in a smart box with styrofoam top and bottom with cut outs to keep the ends of the tubes from moving during transit! The glass is of excellent quality and is ideal for making various party tableware.

Very strong glass. I dropped this glass from a sufficient distance to break lower quality items. It also masters the transition from hot to cold very well with minimal cooling time. Sometimes not. It takes some time to get a good collection with card gas alone. But you can also work a little with a normal propane gas burner. Although I don't recommend it.

So I have to say BS it's actually Pyrex. They become extremely brittle when exposed to relatively moderate heat and then break very easily. Weather or not, they're actually borosilicate glass, I can't tell you that. If so, then they appear to be of poor quality. I'm not an expert, but I've used real Pyrex (borosilicate is actually made by Corning) and it's not. For the price I should have known. Good
