Our duvet covers are the hidden zipper placed at the edge/back of the cover.

 Three advantages：

1. A regular zipper（not hidden）placed on the surface/edge of the duvet cover can break or weaken the sense of luxury of the body.

2. Hidden zippers are covered with a layer of silk, making them less likely to cause abrasions on your skin.

3. The cover that protects your skin also protects the zipper from breaking, granting a longer lifespan and less trouble for you.
