Hi @Eeqmcsq - Thanks for reaching out! While our stores do not specifically have empty fuel canisters for this use, you can reach out to your local REI and ask if they have any available. Additionally, while you are in a store, you can test the size and fit of canisters with different cook sets, which may be able to answer your questions. 

Hope you're able to find a setup that is just what you're looking for!

At REI, we believe time outside is fundamental to a life well lived.
