Please read my self-introduction profile. This is a Nike backpack for children. I used it for 3 years, so it has a fair amount of wear and tear, but I am listing it because I believe it is still in good condition. Please refer to the photos for any dirt or stains. I cannot guarantee the material, but I believe it is made of nylon. The size is approximately 25 cm wide, 15 cm deep, and 36 cm high at the bottom. It will be folded in half for shipping via Yu-Packet Post. Thank you for your consideration.
