This is the popular Felisi model "9237". It's a helmet bag-style tote bag, a combination of nylon and leather. The gusset expands when you unbutton the bottom, allowing it to be used as a large-capacity bag. ・Brand: Felisi ・Model: 9237 ・Color: Black ・Material: Nylon x Leather ・Size (Please note that there may be some errors due to amateur measurements) 　Width: Approximately 45cm 　Height: Approximately 50cm 　Gusset: Approximately 3cm I purchased this previously, but I haven't used it at all, so I'm putting it up for sale. The button on the bottom tends to come undone easily, so the previous owner customized and attached the button. It works without any problems, and the button doesn't come off easily. There is a feeling of use, but there are no major scratches or stains since I purchased it, and I think it's in good condition. For those looking for this, thank you.
