UMETASS(ウメタス) トラベルボトル エンボススケール付き 液体薬用 2オンス/60ml 目盛り付き ポリプロピレン製 広口 プラスチックボトル 容器 キャップ付き 錠剤サンプル 実験用試薬メディア用 (クリア 4個)

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

Excellent product. They are sturdy and leak proof. Just what I was looking for.

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.

Using these as a small travel-sized shaker for my morning Metamucil (psyllium husk).

Great stuff. Thank you.
