Treehouse Stash Jar (4 oz/120mL) Viewing Jars for Herbs, Spices, Coffee, Teas & More, Air Tight Jar, Thick UV Protection Glass, Smell Resistant Herb Storage (Set of 4) (Matte Black)

These little stash jars are made of glass and has child proof lids, cool owl logo on lid. Functions as described, has about a 2 liquid Oz storage capacity and is smell proof! Great gift, and worth the money.

Definitely smell proof!I was skeptical about how smell proof these would be because a couple of the reviews but I got them since they are from a small business and look nice. Then I put them to the test! First I dunked them in a bucket of water and shook them around and no water got in so the seal is tight. After that, I put some spices in and tried to smell them…couldn’t smell anything but I don’t trust my own nose…so then, I let my dogs do the real test! I put some peanut butter in one jar and none in the other. I let the dogs sniff each one and they had the same reaction and were not anymore interested in the PB jar. So my conclusion is, they are just really dumb dogs, and my nose must be permanently broken from covid, OR these jars really are smell proof!

I use these daily, and love 'em. Each jar holds approximately a half ounce of ground herbs, or less if left as natural flower. Makes for a more visually pleasing setup than plain mason jars and the airtight lids and dark glass, combined with some boveda or integra humidity packs, help keep everything fresh. Viewing window is a nice touch too!

These are not really smell-proof but good enough. They're well made and good-looking, etc. I like the child-proof lid feature even though it isn't really needed in my household.

I'm taking away a star because it's not exactly smell proof. I have some flowers in there that smell very very strong (like, they smelled up my whole house when it was in a baggie) and the container at least blocks most of that but you can definitely smell it when you hold it in your hand

These jars are solid. Good quality and they hold in the smell really well. Love that it comes with 4 different sizes too, makes it easy to keep a few different herbs around.

Lids on 2 bottles are not sealing properly. We are unable to use those two.

I bought these for extra storage for my cannabis and it does exactly what it says. It contains the smell perfectly and the cap is also child proof. The glass is of high quality, the amount of time it fell from my hands and didn’t break or even crack. I would highly recommend getting a set or two.
