SP Bel-Art Safety-Vented/Labeled 2-Color LYOB Wide-Mouth Wash Bottles; 250ml (8oz), Polyethylene w/Natural Polypropylene Cap (Pack of 3) (F11643-0238)

I'm sure the other two will work fine, and the have that nifty sliding valve thing so you can use the bottle upright or upside down, but one of the three arrived with half the bottom missing...looks like a short shot in injection molding. I didn't see this, and it caused me to dump about a pint of 99% EtOH on my pants and floor of my workspace. So that's neat.

4 of the twelve ordered were missing pieces, quick turn around with parts tho.

I'm disappointed in the quality of these acetone bottles. The first batch of bottles I ordered had missing pieces. I returned them for a new set and still there was a missing piece. The caps don't fit quite perfectly on the bottles. You have to force the cap to tighten so that there is no gap for air to escape when the bottle is squeezed. I also purchased ethanol and methanol bottles, and those did not have either of these issues.
