I purchased this at a general goods store and have kept it stored in a dark place at home as part of my collection. It is definitely a Sandylion sticker, but the backing card is not from Sandylion. Please check the second photo. Although it is new and unused, there is a possibility of age-related deterioration. Please purchase only if you are not concerned about minor details, as it is a product of overseas origin. The adhesive strength of the sticker has not been confirmed as it is unused.
