Stonylab??

I ordered Stonylab glass stoppers, but they don't have the Stonylab logo on the penny head. I am wondering if these are just some cheap counterfeit stoppers. I like Stonylab glassware and expect to receive the OEM version not some knockoff.I don't know how to grade these other than they do look like glass stoppers.

Tapered Glass Stoppers--you never need them until you have to have them!

Finely made glass stoppers for the 24/40 taper, these are precision ground, symmetrical, and the glass is free of ripples or bubbles. And the price is right. Great for leaving a solution to rest for a few hours or overnight but not for more than a few days as the stoppers will eventually freeze.
