Funko Pops, to me.
I understand that some of them are fairly overpriced, but I also really like them as is. It doesn’t work on all characters, but it sometimes work on a lot and there’s so much representation and variety that it’s good to have a few.
If people want to talk about waste of plastic and vinyl, they should bark at the companies who make teeny tiny figurines that serve no purpose and have so little detail that spending any money on them is a waste.
Get one and (after you tire of that excellent joke) swap it on/off and hide it when people have their back turned like Igor’s hump switching in Young Frankenstein.
