This small Shungite Disc Phone Sticker (2.3cm) is one of the most practical applications of Shungite's properties — simply peel and stick it to the back of your phone to have Shungite's reported EMF-shielding properties working for you wherever you go. Shungite is a carbon-based mineral widely used for electromagnetic protection, and small disc stickers have become a popular and affordable way to bring this protection to the devices we use most. Unobtrusive, easy to use, and a genuinely thoughtful everyday gift or personal purchase.
