Yoga mat EWS

The express list contains a lot of personal information, discarded it could cause leakage of privacy,and bringing a lot of trouble and even dangerous.
This design uses the express list with oxidation faded color-developing agent.Once tearing the film,color-developing agent would contact with oxygen, so that the color would also disappear under the action of oxidation and avoiding the loss of privacy.
However,if wanting to keep the express list,just not tearing the film and the information would not disappear.
