Sanrio Hello Kitty Heisei Retro Rare Hawaii Hibiscus Red String This is a waterproof case to protect your phone from water. There are some stains. It's from the Heisei era. It has a zipper and Velcro, so I think it's waterproof, but since it's from the Heisei era, I apologize if there's a hole somewhere. I don't see any major holes. Because I move often, I may cancel the listing without notice.
