This is an AtRise Nubi bag. Purchased on the website for the regular price of 4480 yen. The size is M. I bought it because I wanted a small bag, but I mostly use other bags, so I only used this one once or twice and then stored it. Please refer to the size M in the 4th image for an approximate size reference. The D-ring is silver. There are no noticeable stains or marks, but it is a used item, so please understand this before purchasing. It will be folded and shipped via Takkyubin Compact.
