8.8oz/260ml 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)

These are nice bottles to store liquids. I didnt realize how big they actually were though. I think traveling with them would be okay. They seem to have a tight seal. They're a great value for your money.

Works great to mix and transport medicinal fluids. The large mouth of the bottle makes adding fluid easy. The bottle seals perfectly without any leaking. Has been in the dishwasher multiple times after use and has not warped in any way. nor have the precision markings erased. Highly recommend and would buy again.

Excellent for my sweet cream when we go out for breakfast, don't have to use any sugar in my coffee. Tight cap and does not spill.... Love it. Great price also. Thanks

Perfect for travel or to store gripe water since those bottles refuse to open lol

Flexible and accurate measurement

I use these for carrying coolant in my car - it has a gradual leak and it is still winter so I hope it makes it to summer to fix. Meanwhile, these let me dose out the coolant neatly, I can track usage very well adding it 100 ml at a time. I'm not going to dock them a star, but it would be nice if they had medieval (fl. oz.) gradations on them as well.

Works great. No leak.

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
