20 Pieces 12 Inches Long Clear Glass Tubes for Art DIY, 12mm OD 8mm ID 2mm Thick Wall Glass Borosilicate Blowing Tubing with 2 Cleaning Brush

Good quality as described. Have and will buy again!

This is the best quality and price I have found so far. It's very thick breaks clean. There's no after smell or taste when it's made into drinking straws. Decorations don't come off.

If you like thick milkshakes and are tired of those crappy plastic straws from the grocery store that collapse before the deliciousness can reach your mouth, these will solve that problem. They're also fantastic for beverages with straw-plugging chunks, as you can use the bottom of the cup to force the chunk into the glass straw. Borosilicate glass is dishwasher safe. It is also microwave safe, oven safe, and torch safe, though after any of those it will need smoother time to cool before sticking it into your mouth or a tasty frozen beverage. The walls are thick enough that these don't feel dangerously fragile, but acts of stupidity can definitely lead to breakage. Ergo, it is your responsibility to make sure your kids are old enough and smart enough to use these as straws, not as drum sticks. They are exactly the size of the hole in a Yeti straw lid, which means they don't have any wiggle room for tilting to the side. I do not recommend these for use with that lid.

Love the thickness of the glass ! Awesome product

Excellent quality unbelievable price on all excellent buy I'd recommend this to anybody in the glass blowing field

Exactly what i was looking for none of 20 were broke and they are the perfect size. Great for blowi g as well as using fir smothie staraws

Very good product

These are NOT borosilicate glass (pyrex), as advertised q. They *are* a nice heavy grade of 00⁰glass, don't break quite as easily, BUT if they break, they fracture and shatter into a thousand random pieces; and, like a pair of pantihose with a run, once it's got a break, it's done. I also notice a lot of them quickly develop vertical hairline fractures, creating a weak stress point in the glass that's all but guaranteed to be the start of a new break. Pyrex doesn't behave this way . 3 stars only for the great price and fast shipping; but this is an inferior quality product.
