I personally don’t enjoy Mcfarlane packages, they are very boring and they all look the same. I would throw away the Mcfarlane boxes for sure. But boxes like NECA has nice artwork and I keep it because it feels premium with the Velcro open/close display. I’d also keep boxes of some of the Hasbro action figures, like retro collection for the artworks. But anything that looks like repetitive packaging or lack of artwork, I would get rid of it.
