you mean "tupperdor". "tubos" are the tubes some cigars come in. storing cigars in tupperware vs. a traditional wooden humidor is popular for enthusiasts because it reduces the risk of mold, is less finicky than maintaining a wooden humidor, etc. I've never messed with cedar sheets in my tupperdors. The bigger issue imo is making sure you properly hydrate your cigars. Most people recommend Boveda packs in the 58%-62% range for tupperdors. You'll also want to invest in a hygrometer: https://www.amazon.com/JEDEW-Hygrometer-Thermometer-Greenhouse-Fahrenheit/dp/B0DXCSXT9X You can obviously go much fancier with all this stuff, but unless you plan to store hundreds of cigars it's probably overkill. Regarding the Zippo -- that's fine. It is recommended you get a BUTANE insert: https://zippo.com/collections/refillable-butane-inserts/products/yellow-flame-butane-lighter-insert-iridescent-green Butane burns cleaner. Lighter fluid will impart a charcoal profile that can be discerned in the taste of your cigar (but I mean, come on, if you're on a fucking ship in the ocean a Zippo with lighter fluid is fine). The Butane insert won't leak though. Zippos hemorrhage fuel so that is a huge negative to them.
