Grade A
I’m using these with headspace vials for samples and so far they have worked pretty good. No leaks after repeated use and they fit nice and snug. Price was reasonable and if I need more I’m pretty sure I’ll get some more of these.

Good product, as described
I put three stars because they ended up being a little bit too small for what I had planned to use them for but that was just because it was a hard space to measure. Product was exactly as described.
