These are actually head massagers or head “tinglers”, which were offered by the company as an introduction gift with the first 10,000 orders of the Husband Pillow. Simply place the tingler on the top of your head and push down. It's a fun gift that tickles your scalp, leaving goosebumps and a smile. The tingler is easily stored in the side or back pocket of the Husband Pillow. Just another way of saying “thanks” for purchasing our best-selling Husband Backrest Pillow with Arms for bed rest, support, TV pillow, bed chair, armchair pillow, bed lounger and just about any bed rest need!
