Time-recording sticker

This time-recording sticker is a product that can record the expiration dates of prescriptions and other products that have validities. It reminds people whether the products are in the time period of usage through the gradual change of color.  Besides, it can also record the course of treatment. And the sticker aids people with visual disorder to distinguish the expiration dates from touching via increasing the sense of Concavo-Convex.
