Ohba Randoseru (School Backpack) Ohba Seikaban (Manufacturer) Dark Navy, Deep Blue Clariano (Synthetic Leather) Used for 6 years with a cover. The flap is very clean. There is some wear and tear on the cushion part that touches the back, the straps, and the inside, but there is no critical damage, so it can still be used. Made of Clariano, it's very light and the construction is solid!
