6 Inches Long 10 Pieces Glass Borosilicate Blowing Tubes 12 mm OD 2mm Thick Wall Tubing Clear Tubes

Awesome, durable, quality

Great glass!! I have dropped them multiple times on cement and they STILL DON'T BREAK NO JOKE! I have broken SO many tubes in the past and they break VERY EASILY, but these don't! Worth every penny!!

It is what they are described as.

Theses get the job done if you plan of adding heat to this, it has very thick-walled glass however it seems to get small cracks in it over time making them not air tight and hence losing your money little by little. These are better than store bought glass tubes but def not the best. Good price point though, I'd grab these again before a store bought one.

Some tubes have hairline cracks in them

This glass tubes worked perfectly.

These are durable they are sized and listed at the right size that they’re fairly cheap price wise always did what I needed them to do. They clean easily just in the dishwasher and there thickness is just listed very durable. They work great

Not the best but not the worse? Glass holds OK on a drop, does start with crack and become weak with high heat. I would buy again tho
