COME DA DESCRIZIONE

As described. perfect.

всё как в описании

What can I say.... It's a stopper :) The rubber is very dense, there is no flash left over on the seems where the mold lines from manufacturing are. One thing I would like to see in the product description are what size stopper to buy for the different sizes of flask's, beaker's test tube's etc.. I just took a stab in the dark and am hoping it will fit...

Чёрные пробки постоянно раскисали и пачкались, эти отлично держат и не растворяются, по крайней мере в спирте.

I'm always looking for stoppers of the right size, so I ordered a bunch of different sizes, and I'm very happy with both the prices and the quality. Couldn't be better.
