I wasn't able to find any information on it on Lolibrary, but it is a fabric shoulder bag/pouch from Frill.

I bought it secondhand from Japan but the previous owner said that it was never used by her, and it was never used by me either.

It doesn't have any noticeable damages, but it definitely has an old feel to it, since it is probably pretty old. So please do keep this in mind!
But I do see something that looks like a smudge on the right ear (pictured) and there seems to be a small mark on the right leg when you look close (pictured).
The backside has some parts where the logo printing seems to be have peeled off a bit or incomplete (pictured).

Approx. measurements:
from ears to feet: 21"
the pouch area: 7x5"
