6 Pcs Borosilicate Glass Tube 12mm OD 2mm Thick Glass Blowing Tubes with Cleaning Brush (Clear,4 Inch)

We all know what we're buying these for. I got the 12" bc I'm boujee and it feels all Gatsby. I've gotten the 1.4 mm thick before from another seller and I like them but they break so easy, especially after repeated heating and cooling.THIS bitch seems indestructible. I put a silicone straw tip on it and it's the best. Delivered very well packaged overnight (I'm in a major distribution area, tho). Probably going to buy another set just to have stock.Bonus: they color blend VERY well for glass blowing so they're actually amazing for all their actual uses.May double as effective PPE if you're of the trap set. But probably don't.

Very nice. Delivers a nice smooth hit. Strong thick glass. Just the right size & sturdy!! Will buy again.

I ordered a 5-pack of clear 4 inch glass tubes and was very happy with the product. The price was excellent for the value. They are thick, durable, and good quality.The cleaning brush/tool that was included is not very strong/long/affective, but it was a nice touch and would be excellent if it was made for the length and width of the tubes I was purchasing.

They are great glass tube's. Tried to break one and couldn't. It holds up to high heat multiple times. Great buy for the price.

Have yet to break even one of them due to excess heat. And I've have them glowing red almost every use and used many times per day. Can't ravenenough about these tubes. You are gonna need a bigger torch and a lot of butane but that is expected.One of the best purchases of the hundreds on Amazon

These should outlast a lifetime supply of chore boy copper scouring pads, but they won't. Your tweaker self will lose them or give them away and need to order more.

Purchased a few times. Last order had 2 cracked.no issues other than that.

perfect would recommend this product
