Nippon Chuko Cat Eye 18mm CE281 These are eye buttons that can be used for stuffed animals. They can be used as blue cat eyes. I bought them as a set, and I'm selling the extras. Some have small scratches from the time of purchase (>_<) I will sell them at a reduced price accordingly. There are 4 in total, and if you need more, I will sell them for 500 yen. Please let me know in the comments.
