Opti-Lube2 PACK - 1 Gallon (128oz) EMPTY F-Style Black Slant Handle HDPE Plastic Jug Bottle with Child Proof, 63mm Neck, Fluorinated Level 9 for Extreme Chemical Permeation Resistance (2)

Purchased for long term storage of biodiesel. Other supposedly non-permeable plastic containers I've used have not lived up to their claims. So far so good with this one after a little over a month. Very early to make an evaluation. But so far, no sticky residue on the outside of the container and no paneling.

If you need these to store chemicals or whatever for a while they're good for sure, with that being said, if you're trying to frequently pour them within 100ml of measurement, they're some of the worst pouring receptacles I've ever had. If it's filled even slightly above that handle line, it's almost guaranteed that you're going to get an overpour. Also, when the containers get low, it can be really hard to get an angle to actually empty them effectively without also risking an overpour.Admittedly, I don't know much about liquid container design, but I have other jugs of a similar size that do pour well and I'm very convinced there's something about the shape (perhaps not enough of a taper leading into an extremely wide mouth). I was actually hoping a wider mouth would make it easier because you'd get less issues with venting and things like that, but that's clearly not the case.

Awesome quality.

Cheap thin plastic.
