Although it's new and unused, I purchased it over 10 years ago. I can't confirm the adhesive strength or the condition of the contents. Some items are unopened, and some are not in bags. As shown in the second photo, one sheet of Pochacco stickers has cuts. Due to long-term storage, there may be stains, yellowing, and other damage. Please consider purchasing if you are okay with this.
