This is an item being sold by a family member. It's from the Tokako Kimishima brand. Since it hasn't been opened, I don't know what it feels like to use. It has been stored at home, so please refrain from purchasing if you are concerned. A Predia sample is included as a bonus. The regular price of 5390 yen is for FTC products. I have a few more Predia samples, so please let me know if you'd like them, and I'll include them as a bonus!
