LB39-500/2 : 500ml Erlenmeyer Flask, with Rubber Stopper, Pack of 2

It's just a flask. Does it's job, does it well. I use them for doing yeast cultures.One of the pair I received had some sort of cloudiness on the bottom edge that looks like it somehow got scratched or scuffed. It otherwise looked brand new so I'm guessing its a manufacturing error or the etching somehow got smeared/blasted into the wrong place.Its on the outside and appears to be 100% cosmetic, so it doesn't bother me.

The flasks arrived without stoppers which were part of the description. One flask had fingerprints from something sticky on the neck which was concerning.
