MASSIVE ROLL measures over 30 FEET in length x 14" in width!  This is a high-shielding electromagnetic radiation protection fabric that blocks radiation and RFID signals.   Whether you you sew it into a bag to use as a liner, wrap your phone, key fob, or other electronics in it, make it into liners for your curtains, or line the inside of a hat, it will block EMF.  We have tested it by placing a phone inside of it, then trying to call that phone from a different phone, and, although the material is thin, it works perfectly! 

This version is lightly textured.  We also have smooth versions available while supplies last.  Other sizes are also available!  

These can be cut to size and used in all different manners. Lightweight but effective.  They come folded as shown.
