Stonylab. Does it again real nice well made. I would buy it again. This from a repeat customer 👍🏻👍🏻👍🏻👍🏻👍🏻

Great deal and good packaging. Showed up promptly and safe and sound.

Nice quality glass with quality ground joints. Works perfectly for testing wine SO2 using the oxidation aeration method.

Came in 2 days and seem almost unbreakable. Not that I am trying. Lol
