This is a square backpack from SiMYEER. I purchased it and used it a few times. The zipper area is dirty due to aging (see photo 7). There is no fading. Material: Canvas Size: 43cm x 29cm x 13.5cm Storage size: A4 size compatible. It is durable and has excellent water resistance. This item is sure to be useful in a wide range of situations, from commuting to school, to everyday outings, travel, and outdoor activities. The inside of the bag has soft cushioning, so it can gently store up to a 14-inch tablet and protect it from dirt and scratches.
