12inches Trolley Bag Unisex Fashion 3D Plastik Cartoon Student School Waterproof Trolley Backpack

Note: The schoolbag just received will not emit light, because the schoolbag has spent a long time in the dark and has no energy. If you want to emit light, you need to absorb light first, such as sunlight, flashlight or fluorescent lamp. The stronger the light, the brighter the light. Noctilucent glows continuously from bright to dark and can be recycled.
