This is our magnetic sleep mask. It has (3) 4000 gauss magnets in our 3 hidden pockets: 1 over the middle of the forehead, and 2 on either side of the temples by the ears, transcranially. This mask is made of a soft velour, very lightweight and comfortable for sleeping. It has a wrap around design for side sleeping. The inside is a 3D memory foam which gives space for your eyes to blink or for those with long lashes. There is an adjustable elastic head band for all size heads and won't pull your hair. It blocks 100% of the light with the nose protector. For those that experience headaches, migraines, travel, meditation, or want better sleep, this is the mask for you. Helps to boost melatonin for improved sleep. Increases cellular energy to counteract EMFs while you sleep. Cleaning the mask should only be done by hand. Magnets are removable for cleaning. The magnets are encased in a waterproof plastic sheath and are marked with a red dot. If you remove the magnet, put them back with the red dot facing away from the body!
