Yes!
@Ke0ncp is correct! Grove bags for curing. Some people try and use them as part of their dry scheme. I don't think they're very effective for that but to each their own.
This last run was the first time I used them as I'm an old school jar kind of guy but, so far, they've worked flawlessly. The flowers have been in the bag for around 3 - 4 months and they're just starting to come into their own. Really nice, clean high that lifts you up on the front end then drops you onto the couch with some beer and pretzels for some multi movie watching!
Super smooth with a nice peppery taste.
