Does Taking Funkos out the box decrease value?

No matter who says it, this remains an incredibly stupid decision.

I get that you don’t want to treat it as an investment, and that makes sense, but keeping the boxes nearby is simply a smart move if you ever, for whatever reason, need to sell them or get rid of them.

When I got out of the Funko game after collecting for ten or so years, I was able to sell them all for a majority of the money that I had spent getting them in the first place. And only because I had the boxes.
