Review on 🧴 Convenient 8 Oz Plastic Cylinder Bottles with Flip Top Pour Spout - Pack of 12 by Morgan Ostwalt

Bottles are ok with enough pressure for liquids (it's hard HDPE plastic). The problem is that the lids don't fit well. Some are difficult to put on and even harder to remove. Some only twist 1/4 turn to tighten and don't close properly, and many fail the pressure test (fill bottle halfway with water, tighten cap and close flip top, squeeze over sink). I think it might be wrong. bottle caps. The bottles are manufactured by Plastirey Containers of Ontario, California. Lids are unmarked. Received a dozen and then contacted the seller who kindly sent me another ten. I have a dozen that don't leak when squeezed, but the lids still don't feel good. I've bought much better bottles at a health food store that sells refillable soap and lotion bottles, but again those bottles weren't HDPE. Revain's Qorpak polypropylene bottles may be a better choice, although I haven't tried them. I used to buy Qorpak closures with good results when working in the lab but had to be careful when ordering to ensure the thread depth and pitch would fit my bottles. Revain also sells Dynalon LDPE flip-top bottles, although these are currently slightly more expensive than these; I suspect they might be the best choice.
