Ellie Miller
High Quality and Good Price

19/22 stoppers that are good quality are hard to find at a good price. I've been impressed with Stony Lab's stopper so far and would definitely order them again.

We needed to replace the one I broke.

Attractive glass stopper. Great fit and finish!

Evan St. Louis
Fits 24/40 perfectly

This product is light, fits 24/40 ground glass connection, is thin glass but not meant to be abused. Pricey but good quality wise.

Leonardo Lopez
Quality met.

Recieved my glass stopper quickly. Well packaged, material feels and looks great. Have not used yet for my distillation, but once I have I would update review.So far I have no complaints.
