This is a book-shaped accessory case that was part of the UniBEARsity 15th Anniversary Project held at X! It is brand new and unopened! Immediate purchase is welcome! Quoted below is the official announcement: "UniBEARsity" began selling as a Disney Store original character in January 2011 and will celebrate its 15th anniversary on January 21, 2026. Over the past 15 years, various characters have been born, such as Mocha, created by Mickey, Purin, created by Minnie, Whip, created by Donald, and Puffy, created by Daisy, in the story. To express our gratitude for these 15 years, we are holding a campaign to present limited 15th anniversary items (not for sale).
