MONOLITH BACKPACK PRO S backpack. Purchased in June 2025 at the Marunouchi directly managed store. Used only a few times for a few hours and then stored, so it's in beautiful condition! Please understand that this is a used item, and only those who can accept this condition should purchase. Tags are missing. As shown in the 4th image, I own multiple backpacks from the same manufacturer, but I think the S size is the easiest to use. Retail price: 53,900 yen Color: Black ☆ Please note that this item is also listed on other flea market & auction sites, so your purchase may be canceled depending on the timing.
