17oz/500ml Wide Mouth Plastic Bottles with Airtight Lids, Graduated Food Grade Leak Proof PP Containers Jars for Water Sample Lab Reagent Liquid Medicine Storage (Transparent, 2 Pcs)

Bottes came in clear wrap. Very nice and accurate measurement. If you want to get 500 ml, that is up to the top of the bottle, not the very top, but at the level where the lower edge of the cap is .

A very good substitute for Nalgene bottles, which have been hard to find lately. They work well (don't leak when the lid is on and the bottle is lying on its side. I use these for water bottles when working out or hiking. They are also less expensive than equivalent-sized Nalgene bottles.

Worked perfectly as a specimine container to take my pool water sample to the local pool store

Great bottle to make and store rust bluing compound in, or to keep isopropyl alcohol in for degreasing and cleaning steel

I really do like this product. The only downside is if you turn the lid too securely it pops off, so it can/will leak. And the measurements on the side are difficult to see. I did use a black sharpie on the side of it to try to mark out the lines I needed to be able to see and that's helped and holding up okay.

Just as good as the "N" name brand. Those who know, know

air tight? water tight? you could stuff a poptart in these things, put the cap on, and i bet the poptart falls out. i actually forgot i even bought these and i know what your thinking "if the ae really that bad how could you forget" well ill tell you how, disgust... shame... im embarrassed to have purchased these. ive tried to forget and its worked so far till amazon had to remind me of this terrible purchase. i know most will look at it as only a few bucks lost but honestly its so much more then that. the lies, the deceitful tactics used to under mind us all to get our dollars. idk what else to say guys, they're trash

Smart bottles , awesome . Thank you
