Communicate / Survival + Emergency / Ec


In our daily life, someone does mind partaking of a drink with others. Therefore, this product can tellpeople if you mind sharing a drink with others or not. This design aims at pressing down adotted line in the middle of the plastic ring which is convenient to be torn off. Without a plastic ring under your bottle cap, it refers that you mind sharing your drink with others. People will notpartake of your drink with the hint for the absence of the plastic ring. In this case, it is embarrassment-free and plays a key effect on interpersonal communication.
