Glass Blowing Tubes, 10pcs 8inch Long Clear Transparent OD 12mm 9mm ID 1.5mm Wall Thickness Borocilicate Glass Tubes for Cut Art DIY

Perfect! High quality, thick and sturdy. Perfect size. No issues, they take heat very well, and easy to mend, shape, close, or whatever else ya gotta do with em. Love the style & color. I'll be ordering more.

Too short to be this weak. Waste of money.

I got this from my husband who likes to blow up blow gas.These are the perfect size for him.He is able to make all sorts of stuff without any issues

These glass tubes are exactly what I was expecting, and they did not disappoint on overall quality. The glass is thick and strong, not easily broken. They are great to drink out of , and should work well for any other purpose you may have for them. They are easy to clean with the little straw brushes. Definitely recommend.

I picked-up these Glass Blowing Tubes for a few projects I’m working on, and they’re very nice; this was a great choice for my needs. I’m just starting to dabble in Glass Blowing, and I was able to create very nice vessel shapes with glass, which is a new skill for me, as I had been forming bubbles into shapes … this is fun! WHAT I RECEIVED: - 10 Re-Usable, Borosilicate Glass Tubes … 2 of Each: Yellow, Green, Clear, Blue, Transparent Black - Cleaning Brush The Blowing Tubes are 8” long, and they feel so nice! They are so incredibly smoothly polished and the ‘lip’ of the Tubes has rounded edges. The thickness of the Tubes’ glass is 2mm. The interior ‘hole’ of each Tube has a diameter of 8mm; but the outside diameter is 12mm. These Tubes can withstand very high heat, up to 2,102 °F; they are dishwasher safe and microwave safe. I will return for my Glass Blowing needs!
