4 Inch Multicolor Borosilicate Glass Tubes, 10 Pack, 12mm OD, 2mm Wall

I usually buy the glass rose from the little corner store- if you know you know- and they break within a day or sooner I'm very hard on them throwing them in my purse or dropping them or scraping at them. The extra half a mm thickness makes all the difference. I used to have to drive into the city to find the thicker ones but found these online and they're perfect if you're looking for a replacement for the glass rose. I don't know about glass blowing or using them as straws- you know if this review is for you. These last me a month or longer even.

I order these for a friend and they love them. Not sure what they're good for.

For the price these pieces are great, solid thickness and length for your blowing needs only down side is I feel like they can be somewhat inconsistent in how they perform but I am new to blowing glass so it could be user error.

These are the perfect size and thickness for the intended use for me. Very well priced and packaged very well.

First, 7 out of 10 already had cracks and scratches from machining. Every single one of them broke without a problem or aggressive use. I will definitely never purchase anything from this company and seller. I would ask for my money back but they have already been disposed of. Literally the worst ones I have ever bought.

These are really great. Instead of one day, one of these so far has lasted 17 days. They are a little thicker than usual but work just fine.

Delivered in a timely manner and handled with care. The product is as described! Very durable and the colors are amazing. Great quality for a low cost. Worth the purchase

I am thoroughly happy with my order. I will say, I was most excited for blue, but it's hard to see through. But that's not fault of the seller. These things are heavy duty and don't break easily when dropped (a huge advantage). Currently using a yellow one, and it's doing its job!
