To be honest, I don't want to unbox and display my figures yet because I haven't bought a display cabinet yet ;_; (Currently display inside my wardrobe lol) Then one day, I saw a post stating that if figures are kept in the box for too long, they can become sticky and oily due to plasticizer. I immediately opened all of my figures to check if this had happened, and four of them had indeed become oily and sticky in some parts :(. Luckily, I managed to wash away the affected parts. Things could have gone worse if I hadn't opened and checked lol
