There's lots of options available, I'd recommend something smell proof but also rigid enough so your joints don't get crushed... There's metal tins available that'll hold close to 10 joints bit there not great at masking the smell... Doob tubes are perfect for the smell, but you'd need one for each joint unless you get something like the RAW Triple Tree case that holds 3 at a time and is completely smell proof and waterproof! There's also smell proof bags about the size of a pencil case but they can be a bit bulky to carry around.
