Formline 1/4 oz Smell Proof Container (100 ml) - Airtight Stash Jar w/Black Glass Preserves Contents and Odors Inside Includes Discreet Travel Case to fit Bags or Backpack

All this is, is a really sturdy, thick-made jar. I think I could drop it on concrete and it wouldn't break (haven't tried). But that's all it is really. I see absolutely no reason why this would be "smell proof." There's nothing fancy about the seal or lid at all that I can tell; in fact, it easily gets bits around the top edge of the jar and threads so I can't imagine why it would be smell proof at all. I use it for pipe tobacco ... because doobie smokers get better toys than pipe smokers these days ... I mean, Dunhill of London doesn't have a nice little 3 1/2" jar that I can keep my Navy Flake in. Also, the zipper case is extra credit since that is extra nice; I didn't need a zipper case, but I use it anyway since it's so luxurious. Finally, it was kind of dirty when it arrived; it was still covered with some kind of wax -- maybe it was the mold release compound or something, but it required a good, vigorous polishing with a rag before first use.

The jar is overall nice and the padded case it comes with is very nice but the big problem with the jars is if you have finely ground herbs the lid doesn't seal well and they will get out and around the threads. If those herbs smell then they won't be contained in the jar anymore and thus neither will the smell. Compared to the Masterdam jars of the same size and shape, these aren't as nice. Again the little bonus things it comes with are nice but I honestly doubt I'll ever use them. DO yourself a favor and go but the Masterdam jar that's the same size and shape.

Loved these jars like crazy when I 1st acquired them. Turns out the zippers and the leather case do not mix. The cases have fallen apart on all 4 jars. They were perfect but made pretty damn shotty.

Works decent some smell still gets out if its strong but keep the smell lower I love the case tho I

Very Good

Better then the big jar

They are extremely great for price but they are extremely hard to close the container. Almost like like don’t fit

Completely smell proof. I love the case. I dont have to worry about the jar breaking when it in my backpack.

The media could not be loaded.  Super sturdy glass container, I love the case it comes in. Seems to be smell proof, but not super concerned since my stash bag is smellproof! Overall good item! Also, I can fit about half an ounce in the jar so it’s the perfect traveling container when you don’t want to bring your whole stash with you!

This is a nice looking product but unfortunately, it does not work to conceal the smell.

These jars feel good, with thick strong glass and they seem to keep smells in, I only wish the brand was not printed all over it as this detracts from its appearance. Travel case is a nice bonus!
