Glass Blowing Tubes, 10pcs 4inch Long Multi-Color OD 12mm ID 8mm 2mm Wall Thickness Borocilicate Glass Tubes for Cut Art DIY Blue Green Pink Yellow Transparent Each Color 2 Pieces

Definitely recommend for the durability, the value for the money, the functionality, as well as the size!

I needed a piece of glass tubing to repair a project. This item was absolutely perfect. The clarity is excellent. The tube thickness was ideal and thick enough to be strong but perfect for see through. The ends are nicely rounded to avoid cuts or chips.

I didn't realize these didn't have bottoms to them. My bad. So.... I don't know what to use these for. But, they do seem to be well made. I'm not a chemist or dr!ug maker so I honestly don't know what to do with these besides use them for short fat straws? The box they came in was great, nothing was broken upon arrival.

Just what I wanted and packaging is great

These glass blowing tubes are well crafted and good quality glass. All edges are smooth. The walls are even. They come packaged very well. I had no breakage issues. All the tubes were straight and without flaws. Good value.

Although these were packaged perfectly, each tube had flaws. Wouldn’t hold the gases I tried and some liquids seeped as well when heated. If you are using for solids or thicker liquids may work, but each one seeped matter by one or 2 uses. When heated the flaws got worse.Wish they had because these were the exact size I needed.I wouldn’t recommend if you are using heat or thin matter.

These Glass Blowing Tubes are very nice, well made, well designed, and high quality. Overall, I think they're a great value for the price - especially considering there's 10 per package. I highly recommend!PRODUCT: "Glass Blowing Tubes, 10pcs 4inch Long Clear Transparent OD 12mm ID 9mm 1.5mm Wall Thickness Borocilicate Glass Tubes for Cut Art DIY"

I'm not even a beginner when it comes to working with glass and I'm unsure if the propane torch I have will be sufficient. I'm hoping to use a drill and the torch, but I still need to work out exactly how I shall work with these. These arrived quickly and in perfect condition. Any that don't survive will be all my responsibility.
