Smell Proof Storage

Storage splits by format, not by size. A keychain tube or a puck carries a small amount without putting a jar-shaped lump in your bag. A jar keeps a larger amount fresh where it sits. A carbon-lined wallet or case handles everything that isn't rigid. What they all share is a real seal: an O-ring that compresses as you twist the lid shut, a child resistant push-and-turn, or a vacuum pump that removes the air entirely. Aircraft-grade aluminum and borosilicate glass, from keychain size up to 1200ml, finished plainly enough that nothing on a shelf announces what it is.
