Unicorn Eye Patch for Lazy Eye Training, Made in Japan

I purchased this from a shop called Kyoto Hanari-san on Rakuten. It was sold for around 1500-1800 yen, and I bought the regular size. Since this shop makes each item individually, there may be slight variations in size.

My child has incurable amblyopia (due to having their lens removed during surgery for cancer) and didn't wear it much because it didn't improve. Unlike sticker types, this is a type that attaches to glasses, so children are less likely to dislike it.

Since this has been barely used, I would like to pass it on to someone who needs it.
It has been washed before being put up for sale.

The following is a copy of the shop's description:
[Product Description]
We created this to solve problems such as children disliking sticker types, or peeling them off immediately after application. Each item is handmade with a design that is easy for children to use themselves, and made from gentle cotton material for their skin. This is possible because we are a sewing company. We have paid attention to every detail, combining appearance, functionality, and design.
