i use mine if i can find them reliably for cheap or have duplicates already (i also keep a sion pripuz ticket thing in my phone case because it's clear/glittery)
some of them i got used in pretty bad condition like the pripara metal ones i found have a tendency to yellow pretty bad even if they weren't opened so i feel even less bad about using them
you can also just bootleg ones if you don't want to use official merch, many options if you want to go out and about with merch stuff
