Why a Japanese Transformation Mask box moves differently to a Japanese Transformation Mask card
A card is worth what the card is worth. A box is worth whatever people think is still inside it, so a box price falls while Japanese Transformation Mask is in print and starts climbing once it is not. That is why a two year old box can cost more than it did on release week, and why buying sealed at release is usually the worst moment.
