This is a set of four 2-way alls. All were purchased at Akachan Honpo. The size is indicated as 50-60cm. They were worn quite a bit, so there is some wear and tear, but there are almost no noticeable stains, and I think they can still be used. Only the hedgehog one has a slight stain on the collar (see photo three). They are all thin long sleeves, so you can adjust what you wear underneath and use them for a long time until early spring♪ Basically, I'd like to sell them as a set, but please consult with me if you'd like to purchase them individually.
