These are actually head massagers or head “tinglers”, which was offered by the company as a free product 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 any just about any bed rest need!
