Was going to return these because they came poorly packaged and 3 were chipped. But decided to keep because too much trouble returning and glass is thick & nice. (Luckily only chipped at ends, if in middle would've been on its way back to seller.

Exactly what I needed. Good quality and I think it's reasonably priced at $10 for an 8-pack. I used this for glass crafting with an oxy torch and it worked exactly as borosilicate glass should.

Very thick and strong durable quality glass. Long and fairly easy to blow. Works as expected. Recommended

These are perfect for kids travel cups. They're easy to clean, can be put in the dishwasher, and unlike the plastic ones, you can see if they have schmutz in them.

I know this set of glass straws is intended for cocktails, but I ordered this set to experiment with glass bending/blowing.The inclusion of two cleaning tool is a nice gesture. I grabbed this set for about $13 bucks.....that means each tube is less than a buck!I will update the review with images once I start my project!
