The reason why the nipple cover can be well fixed on the human chest is that there is a certain amount of glue on the women nipple cover to fix it. These glues are different from ordinary glues. They are specially treated and processed and have a strong viscosity. Even in the presence of water or cleaning agent, the chest sticker will still have a strong viscosity, so it will still have viscosity after washing.

The cream should be washed with shower gel. Wet the cream with water, rub it with bath gel, and then rinse it with water. The cream after washing and drying should be pasted or put into a clean plastic bag to prevent dust or other dirt. In addition, the cream should not be worn for more than 8 hours

How long to use the sticky nipple cover depends on the quality and care. If the invisible chest sticker of ordinary quality is not well glued and is not cleaned and protected by the user, it may not stick much after carrying it once. However, if the invisible chest sticker of good quality is used sparingly, it can be cleaned and dried as soon as possible after taking it off to avoid dust and other dirt affecting the wearing. It can be used repeatedly for about 20-50 times.
