STANDARD ISSUE SIGNAL CONTAINMENT.
Three sizes. Three devices. Total isolation.
The TINFOIL Containment Sleeve set provides Faraday shielding for your most common devices — phone, tablet, and laptop. Each sleeve is constructed from dual-layer metalized shielding fabric that blocks electromagnetic signals across the full consumer spectrum.
