HOW TO USE: The round silicone inside the box is placed at the entrance of the ear canal. It is pushed very gently. Then, the flat side of the band is held up and placed in the center of the forehead. With both hands, the pinna is closed, applying pressure to the pinna and the silicone. The male and female Vekras are placed on top of each other at the nape of the neck and are then joined by pressing firmly. The individual will have no difficulty adjusting the required tightness (pressure). Its special design allows for the desired amount of pressure to be applied to the application area. It is available in three sizes, depending on head and pinna size: (S) for ages 1 to 4, (M) for ages 5 to 10, and (L) for ages 1 to 4. Made for ADULTS. Silicone should be washed with shampoo in the palm of your hand after each use and stored in its plastic box. KEEP AWAY FROM CHILDREN. Application to children should be done by adults.
