6 Inch Borosilicate Glass Tubes, 10-Pack Clear Tubing, 12mm OD, 2mm Wall | Glass Blowing Supplies, Clear Tubes, Heat Resistant, Fire-Polished Ends, DIY Glass Crafts, Laboratory Use

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

Good quality

These are great for making wind chimes since they can be cut with a small diamond blade , or for small water features since they dont rot or rust along with fertilizing potted house plants since you can place it in the soil down to the root and add liquid fertilizer or water so it stimulates the roots and lighting projects as well , very versatile.

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

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.

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!!

I don’t know if they sent me the wrong time, but these are not Borosilicate, and therefore does not meet my needs. These are just plain glass tubes.
