Phone Signal Blocking Handkerchief Gift

For the groomsmen

A witty idea, a clever presentation, plus a whiff of scientific gadgetry? Love—I'm ordering this for all the guys on my list. How it works: Tuck the mobile-phone-signal blocking hankie into your pocket (or lay it on the table to ensure your dinner guest is sufficiently appreciative of the courtesy). —JR
