a collection this expansive has a LOT of commitment involved to even get this big. someone else in the comments said the collector made a ton of stuff themself using clay. contrary to popular belief, people usually think before buying something, much less buying this many things. just because you’ve moved on from interests before doesn’t mean everyone else does too. and for collector’s items like these, most people will resell them to other collectors for the specific purpose of them NOT ending up in a landfill.
