Stash Jar - Airtight Smell Proof Aluminum Herb Container Waterproof, Scent Lock Odor Protection. Beautiful and Discreet Metal Design. Store your Herbs and Spices Securely. Perfect Size for Travel (1)

I don't trust these for being waterproof on the trail,good for limiting food smells and keeping animals at bay.These rely on a rubber O ring and that can be tricky to get seated,being that many people over tighten the seal.These are not as effective as using a sealed box such as a high end cigar box.Boxes use clamping action for compression against the rubber seal.A screw down system is slightly more prone to user induced failure.In choosing a sealed jar, Pay attention to where the threads are located.These are threaded correctly, but I have encountered occasional cross threading issues.Likewise if you are pouring out supplements, you want a smooth inner surface with no threadsto get clogged with material.These function well.

Too short and stout for pouring ...or AA batteries.These are nicely made and not too heavy,but I don't like the stout models.We started using the thin and tall models because they pour better.

This is very nice and its compact for travling. My strong herb doesnt smell through the container. It also came in a few days.

Great stash jars. I use them often and have used them as gifts to others, friends love these and so do I!

I don’t know about smellproof... but pretty close. Love these little jars.I don’t use them for travel. Definitely lighter than a glass option but heavier than plastic.

Excellent product. Not like the cheap ones you see in store. Truly airtight

Great set! Lovely range of sizes. Extremely smell proof and effective.

A little smaller than I thought, but still works great; just as advertised.
