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.
First card free with the purchase of a Captains of Crush Gripper (we'll include it automatically); one free card per customer.
1250-C (.25 lb.) additional cards $3.00 each
*Proof of purchase may be required.
