Nice and thick exactly what I needed
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.

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

Worst product ever
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.

Very good value

Very sturdy
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.

Thick glass
These are not like the rose in glass tube. This glass is twice as thick. Depending on what you need them for, they maybe to thick. ๐คท๐ผโโ๏ธ

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!
