Glass Tubes 12 Piece, Reusable Glass Straws 4 Inch Long, OD 10 mm, Thickness 1.5 mm, Industrial Borosilicate Glass Tubing for Short Cup (10mm-4IN-Clear)

perfect OD good intake and MM wall thick for long last..

Package arrived quickly in a thick cardboard box. Inside, glass tubes snugged nicely in bubble wrap with zero space for the glass to move around and break. I use these as a guide for flux core welding wire and they are unaffected by heat and don’t break if dropped. Great product and thicker glass than I’ve seen in other brands.

They are fine for the price may be a bit better

These glass tubes arrived very well packaged and all of them unbroken. I use them to blow glass and these tubes worked great for that purpose. They take heat well and don’t break and are very strong when I am done. I do believe they are borosilicate and I would highly recommended them.

Different material than used to be. Fragile. Splintered. Cracked.

These borosilicate tubes are the only way to start a serious weekend. They more than were the life of the party,but kept it all guccithroughout the next week or two, including many accidents on pavement and hard counter tops. Took a hitting and kept on ticking.

I needed these to be the 1.5 mm thick tubes which aren't as common as the 2 mm, that's why I bought them and they are totally the 2 mm!! Even look at the picture they show, it's actual size and it's two mm indeed. I'm so disappointed, completely incorrect thickness. I should have stuck with the last seller. Way too thick for my use. If you know, you know. Get 1.5 there's a seller with multicolored that includes pink and those are actually 1.5

Packaged well, sturdy glass.
