Autism, intellectual disability, epileptic seizures, allergies, asthma, etc... If there's anything else you'd like to see, please feel free to send me a message! If I can create something that's hard to find... I'd be happy too. [Set Contents] Case Charm Sticker to write your name, address, etc. ★Please choose which illustration you'd like, and your gender! To prevent the paper from moving around in the case, it's attached to thick paper. For those who need it, I've also included a sticker where you can write your address, etc., so please use it by sticking it on the back! A charm also comes as a bonus ⭐︎ I hope it helps those who use it, even a little. We will ship it so it won't be damaged, but there may be some minor scratches on the case from the beginning. Please note that we cannot exchange them.
