Create your own Can Knocker Game at your next Birthday party or school carnival. Simply assemble these into a pyramid shape and throw bean bags at cans. We recommend buying either our GS94 or GS95 Vinyl Bean Bags to create your Can Knocker Game. You can use a card board box to set the cans up in so they will be contained for easy collection and set up for your next carnival guest. These empty cans are made out of tin plated steel. These cans weight 1.9 oz each. Size is 3 1/2 Tall x 2 7/8 Diameter.
