Review on 🔥 Borosilicate Tubing for Glass Blowing - Pyrex Piece by Sean Burnett

Mostly used for either science projects or love roses or pens as they call it where I live. They are definitely thicker and all five were in excellent condition. I even accidentally dropped one when buying it when I opened it and hit the wooden floor without breaking or cracking. I only recently bought this so maybe they definitely haven't upgraded plastic but definitely borosilicate or at least stronger than cheap gas stations that just crack from heat. With them you can really vaporize and not worry about breaking the glass. I haven't had a single break in weeks and I've spent quite a few. Depending on your usage, some of them may not be suitable.
