After searching for a while, I finally found these stoppers and I am SO HAPPY that I did. We have a ton of random sized glass vials, jars, decorative containers, etc. and not a single one still had a stopper - luckily these types changed the game with their versatility and beautiful look. The fact that these are a dark blue also makes the glass pieces stand out even more, adding to their appeal. Very well made and durable!

These stoppers were exactly what I needed! They were firm but pliable. They were uniform in size and shape. The neoprene provided enough grip to keep the stopper in place. No leaks were noted either so excellent product on all accounts.

No problem with the product itself, or the vendor. However, it did not meet my needs, my mistake!
