Features a puffy Thomas the Tank Engine patch. The main pocket opens with a double zipper, making it easy to open wide and use. The back is made of breathable mesh, which prevents stuffiness, and has urethane padding to reduce strain on the back. Reflective panels on the shoulder straps and other areas glow in the dark, and it also has a safety belt for secure fastening. There's also a loop for attaching a buzzer or keychain. Please refer to photo 8 for the size. It can still fit two 2cm-thick picture books and notebooks used in elementary school. Some stains are visible on the front and inside back. The name has been erased with a marker. Will be folded compactly for shipping. (The books and notebooks in photo 8 are not included) For those who understand that this is a used item. Thank you for looking.
