So, for context, in 2018 I packed up and stored my amiibo collection until this year (2025). Of my entire collection, basically every amiibo released up till 2018, the only 2 amiibos that have a yellowed box are the Pit amiibos.

They were stored in a garage in a box. Those two specifically were at the bottom in bubble wrap in said box.

Of all the amiibos, only their boxes were yellowed... is this a sign? ????
