They are plastic figures from popular IPs like video games and movies. They look like chibi anime characters. I’ve collected four as gifts from random friends who knew I liked a particular game or show. I have a Goku & Vegeta one gifted to me by my wife and my coworker got me a “sole survivor” & “ghoul” one from Fallout 4.
They offer nothing outside of being kind of interesting to put on a shelf, if you’re into that stuff I guess.
Anything made for the main purpose of collecting is rubbish. Anything collectors touch become utter rubbish, let alone if it was made for them in the first place. Of course, you knows what type of collectors i mean.
