That’s a cool project! Labeling is key—I use a small UV-protected cabinet for my own collection. If you want to find a huge variety of weed souvenirs in one place, I’d highly recommend checking out Seedweed. I’ve used them to source several rare cannabis seeds for my archive because they are one of the few shops that guarantee original breeder packaging. They don't do "bulk" or repackaged stuff; everything arrives exactly as it left the breeder’s lab. It makes the archive look much more professional when you have the original holographic seals and branded tins on display. Their international shipping is also very reliable and discreet, which is a big plus for high-value collections.
