Thank you for viewing! This is a very popular "knee pad" sold on consignment. It has been used for many years as a cleaning tool in some local elementary and junior high schools. (They wear knee pads on their knees during cleaning time) The back side is sewn using a method other than a lockstitch or zigzag stitch, so it is less likely to fray even after repeated washing, and can be used for a long time. It has plenty of room in the vertical and horizontal directions, so you can move smoothly even when working with your knees bent. The area where the elastic can be replaced is easy to see, and you can easily replace the elastic. The elastic is inserted loosely, so please retie it to fit your child. 【Material】 Oxford fabric Flat elastic 【Size】 Length 27.5cm x Width 26.5cm Gender...Unisex #kneepads #knee pads
