This is a one-of-a-kind item that you won't find anywhere else. I've made a sturdy knapsack using a thick mesh-like fabric and a nylon lining. Each drawstring is 200 cm long and lightly tied. Please adjust the length to your preference. A4 size items will fit. Size: Body: Height: Approximately 41 cm Width: Approximately 30 cm Depth: Approximately 8 cm *Please understand and accept that this is a handmade item, so there may be slight imperfections such as uneven stitching, double stitching, and re-stitching before purchasing. Thank you for looking.
