Karter Scientific2000ml Narrow Mouth Erlenmeyer Flask, 3.3 Borosilicate Glass, 213G15 (Single)

not for precise work a bit uneven but strong because of its thickness

Poor quality! The rim of the flask is full of little bubbles and pits. I plan to use it for yeast starters but its gonna be hard to keep clean...

Came quick, no damage. I used it once so far, didn't break it so that is good. Lowest cost one I have seen, don't see Pyrex label on it anywhere, so being extra careful with it.

It’s perfect

Very solid product.
