This is a Montbell children's backpack. It's a large 40L backpack, suitable for overnight training camps and the like. It was used by a child for hiking and camping, so there are some scratches and scuffs here and there (e.g., on the straps). I think it's still in good condition and can be used, so I'm offering it to someone who understands. Also, I removed a tag with a name written on it from the underside of the top flap (see photo 3). *Purchase price...unknown (This is likely the successor model, for reference >>> https://webshop.montbell.jp/sp/goods/disp.php?product_id=1133312)
