This soft blanket is perfect for your lap and blocks 99.9% of harmful EMF radiation emitted by electronic devices. The blanket is particularly suitable for daily use and is also antibacterial and odor-neutral. It is suitable for older children or grandparents as well. The blanket should not be washed for more than 30 minutes unless cleaned by hand. The shielding effect can be reduced by body sweat, abrasion, or excessive washing and drying.
