OESS Thick Glass Round Media Storage Bottles with Blue GL45 Screw Cap Graduated Borosilicate Pyrex Glass Container

I bought a set of these bottles, and the equivalent Pyrex 100ml Round Media Storage Bottle which is about 50% more per unit at the time of this writing. I can't tell the difference in quality based on my visual inspection. They feel just as solid, however, I've not tested them for shatter resistance, temperature rating, or pressure rating, so consider that if you are planning to use these for anything mission critical. Personally, in the end, I prefer the Pyrex solely for its orange cap.

Absolutely the best bottles I have in my collection no drip sanatary thank tou

quality was exactly what we expected.

Sturdy glass. Good product!!

Good sturdy

Quality,nice look. Just the right size.

The containers are very heavy glass and constructed well. I bought these for liquid travel containers because they meet Canadian TSA requirements of 100 ml and the volume labeled on the bottle. The problem is regardless of how tight you screw the cap on they leak in transit. Not a good fit for transporting liquid.
