This is a WILD price for so many of these little bottles!I normally make use of the 500 and 1000 ml size, but these seemed very useful for some other things around my workshop.Despite the title, I still wasn't fully prepared for a full dozen of them.They're not listed as "self venting" so hopefully they won't drip condensate, the way some cheap bottles do. But these are cheap enough it'd be hard to complain even then.
