I used this backpack for two years to carry my child's lunch, spare clothes, towels, etc. when they went to daycare. It's the perfect size for children up to kindergarten age to carry on outings. I washed and stored it at home after use. It shows signs of wear, and I've circled the areas of particular concern in white in the photos, but it's still usable, so I'm selling it. One zipper is missing, and the detachable accessory is not included. The mesh tops of the pockets on both sides are stretched. There is a large mesh pocket inside. There is a front pocket on the outside, approximately 15cm x 16cm x 2.5cm. The backpack is approximately 34cm x 23cm x 10cm. Please take a good look and purchase with your understanding.
