All cover / Bottle lip

All cover
All cover

To address the problem of both men and women being drugged in bars , we created a designed product of a bottle lid. Based on the issue of gender equality, this designed product of bottle lid can be used by both men and women decently.
We hope that this new product is much smaller than usual size, and we also hope that users will not feel uncomfortable or embarrassed when using this new product.
Therefore, this new bottle lip is designed to swell in water and is made of transparent materials in order to minimise the risk of being drugged in bars.Drugs can be blocked by a transparent material when tossed into the water
