  • what is the substance that makes the blocking possible ?

    I see you listing 3 on your blog: 1. Japanese linen fabric 2. High performance washable shielding fabric which provides 20-35 dB from 100 MHz to 2.2 GHz, and residual prformance up to 10 GHz. 3. Japanese 100% cotton, at your own option choosing from our list of fabric.

    which one is it?
