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

I am impressed with the quality of these jars. They seem to hold the smell really well. It seems the more you use them little pieces get around the edges of the jar so maybe that's where some people smell it. I like the window and black jars. The logo is cool.

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!

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

Price is on point for similar products. Child safety lids and viewing window on the side. All of these advertised black glass are wrapped with a heat shrink material. These have good seals meaning that you can’t accidentally peel off the covering. Others I’ve ordered weren’t as well made. Box came in a little rough looking, but product is of good quality.

The jars are small. They absolutely don't hold 4ozs, as each one could only hold a quarter of an ounce.

These jars are nice quality and the viewing glass is great, but are not fully smell proof. I have 12 of them with bud in them and when you walk into the room you can smell it a bit.

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.
