Great for storing coffee
Great product. I use them to store coffee beans in the freezer. Fits about 20g per tube. They have lasted a while, they are dishwasher safe, and they hold up to the freezer. Fair price and very useful.

Solid with good seal
These are really nice tubes that should meet my usage goals quite well. I purchased them to keep single doses of coffee beans as well as cooking oils, etc. on camping trips. They are solid and seal very well.

Do recommend.
Edited. In hindsight, I'm just sick of cleaning my tube holder. I'm not even sure a flat base tube of this size would fit in my centrifuge. Please disregard the below comment. (Edited:The only thing I would like more is if these had a flat base so I could sit them down upright, outside of the centrifuge.)

Tight lid, measurements all the way down tube
We rely on these tubes for multiple reasons; a super tight leak proof lid and the measurements go all the way down past 1/2ml which is super hand for the small amounts of liquids we need to collect and analyze. Plastic is heavy duty; haven’t had an issue with cracking like some other brands. Lid is super tight; great for liquids.

Larger than expected
I bought these, believe it or not, to collect urine from my cat who needed frequent urine tests. These hold a lot of liquid (much bigger than I pictured in my head) but the screw top is strong and won’t spill, unlike other tubes I’ve used. Very durable, and the vet was impressed when I handed her the tube, since it looks very professional! These will last a long time in our house, and they’d be great to use for arts and crafts, science projects...and not just for collecting cat urine.

Fasse advertising as it is not sterile
Used almost 30 of these and there is always contamination and bacterial growth... so it is not sterile. The problem is that the cap does not stay fit and opens enough to let air get in the tubes
