They're pretty much the same animal. Perfectly fine for storing for a few years. If you're storing for the ages, forget about tins, any tins unless you seal the tins in something else, and just jar the weed. As for tins, cutter tops are good for long term storage.Are the HU Tobacco paint cans sealed? Or are they like the unsealed Peretti cans?
FWIW, Reiner uses the same style paint tins and I opened up a 10 year old tin recently and it was perfectly still sealed
