AOMI 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.
