Easy sunning / Bedding

Easy sunning

The goal of this product is to remind everyone to clean their duvet. We design some simple patterns and paint it by hydrochromic ink on the duvet cover. This can not only remind the users to clean the duvet but also help then to find the zip slider on the cover.
The water absorbency of every material is different, so people are confused about the time to clean the bedding and pillow. But this problem could be solved by using hydrochromic ink. When the humidity of duvet is too high, the ink will become transparent and the patterns will appear. The patterns will spread from the zip slider to the upper right side of the cover.
