They work as advertised used for one month and made my flower that was dry come back and saved it. 10/10 will purchase more for sure. you get the glass the marker the dry erase lid and capsule for a great price.
I've only had mine for about a week now, but it's doing the job so far. I wanted an alternative to humidifier packets and this seems to be a great solution.
I also like the that the jar is wider than my previous containers, much easier to get my hand down into it.
I will probably buy a second one in the near future. Overall a really nice option if you are looking to keep your cannabis fresh.
Decent size, can hold an ounce of ground herbage. Thick silicone cover is solid and gives good protection for the jar inside. I might buy some more soon.
