It IDs you as a special grip guy/gal with membership in the largest, strongest grip community in the world.
It’s the platinum card of the grip world and the official width for certification attempts, too: keep it in your wallet, hang it on your gym bag, or us it as a luggage tag for above-the-crowd recognition. Certify on the No. 2 or No. 2.5 (women), or the No. 3, No. 3.5, or No. 4 and your card gets a special sticker; each card has a unique number and a signature band.
