Anyone found good smell-proof storage for snacks or herbs?

Bit of an off-topic question, but maybe some of you can relate. I’ve been trying to find a good solution for storing strong-smelling snacks and herbs (especially when traveling or storing them long-term). Most of the regular zipper bags I used before either leak odor or don’t seal properly after a while.

After some research, I came across these custom smell proof mylar bags that were surprisingly effective. They've got a thicker material and better seal than the basic stuff I used to use. I’ve tested them a few times now, and so far—no complaints.

Just wanted to drop this here in case someone’s also dealing with strong smells and needs a discreet storage fix. Curious if anyone here has other recommendations too?
