This is an ECC Junior lesson bag. It's not the current design, but one designed by Osamu Harada. My son used it for about six months when he was a kindergartener, but I mostly carried it, so it's in good condition. It was then stored in a box for about 15 years. There's a faint pen mark on the yellow circle, but it's barely noticeable. It's a 3-way bag that can be carried by hand, over the shoulder, or as a backpack. This is perfect for a child's bag, or as a collectible item for Osamu Goods fans.
