Thank you for viewing! I made a large knapsack that can be worn over a school bag♪ Mondays and Fridays are when there are a lot of things to carry, like indoor shoes, gym clothes, and lunch clothes! When that happens, it's convenient and easy to put all your belongings together and wear them over your school bag, freeing up your hands(*´∇｀*) In my house, we call it the "Monday/Friday bag." When not in use, you can fold it up and put it in your school bag to take it home! Size: Height: Approximately 41cm Width: Approximately 42cm (There may be slight variations) Please adjust the straps to fit your child. Made with Oxford fabric, single-layered. ⚠️There are marks from the marking pen, but they will disappear after washing, so please be aware of this. ⚠️This is a handmade item, so there may be some stitching errors or distortions. Please understand. Please refrain from purchasing if you are looking for a perfect item. ⚠️There are no discounts for handmade items, but if you purchase multiple items, we will adjust the price to reflect the shipping cost.
