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

Great Martini straws. Easy to clean. The 10 inch ones are great for smoothies too.

Awesome, durable, quality

Good quality

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.

Bought theese to make a level sight tube for a maple sap evaporator. Works well and did the job for me. I put it in a ½" s.s. swage lock elbow wit a silicone o-ring instead of the ferrule.

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.

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
