Not a lot to say about these glass tubes other than their are easy to work with even just a propane torch. Great for a beginner to try out to see if they want to blow glass without breaking the bank. Kind of on the shorter side but they are fine for a single very basic piece. The glass is durable as far as glass goes and the thickness is uniform. I'd recommend them to any beginner who needs some glass tubing to start off with. You can't beat them for the price.

I just got into glass blowing, and I really appreciate the skill. I know I have a big learning curve, and I need all the help I can get to create a quality product. I like these tubes, because they are durable glass that can tolerate a lot of my novice mistakes. Another good thing about them is my finished products are often praised higher than they should be, simply because of the glass quality. I had a lot of fun with these, and I will be getting a lot more.

It’s thick and strong. Definitely easy to clean hence it’s wide.It’s too short for what I need but overall it’s a very good straw.
NO BS REVIEWS!

Glass tubes for glass blowing. They come wrapped snugly together in tissue paper. The glass is rather thick and need something stronger than just a regular tank to heat these enough to melt and work with.

These come nicely packaged and are great for a highball glass. Size is consistent and they all arrived intact.

My kids have broken more regular size glass straws than I can count. So happy I found this little people size that are less prone to breaking once dropped. We haven’t lost one so far.
