I purchased this new at a store last year. I've only tried it on and haven't actually used it. Because it's a high-spec model (TS WHITE), the nature of the fabric gives it a wrinkled appearance. The size is 45cm back length, with an XS hip belt. (The hip belt can be exchanged for other sizes) I will discount it by 1000 yen for those who don't need the hip belt. I've stuffed it for the photos. I've disposed of the packaging bag, so I will ship the backpack itself, packed. Thank you.
