Poor example of borosilicate glass. super thin, extra soft, cracks while cooling 9 times out of 10, which it��s not supposed to do very disappointed

So far, so good. Using to root cuttings in oblong vase on windowsill. Works well.

the d4 barely barely fits but even with a slightly oversized d20 all the dice fit nicely. Its a bit longer than I needed which I was aware of, but I even after hours of searching I could never find exactly what I wanted that didn't ship from china and take 2 months to arrive.<br><br>These will work nicely, though. I ordered size 15 natural corks from etsy for these. probably could have ordered a 14 to make them stick down in the tube better and fill that gap in the top. Might pour a bit of resin down in the bottom instead.<br><br>they are the correct 30mm on the outside. walls are 2mm thick so its 28mm usable space. All test tubes arrived safely and unbroken. They're not super thick or durable, about like a sturdy eggshell, but they don't feel cheap.<br><br>overall pretty nice would buy again or recommend
