Thirty six thick, foil detailed cards making 18 matching pairs, painted as an underwater scene: hammerhead sharks, angelfish, an octopus in a shipwreck, a diver, a little yellow submarine. The card stock is closer to a drinks coaster than a playing card, which is the point at this age. Small hands can pick one up and turn it without bending it.

Lay them face down for a proper memory game, or deal them face up for a toddler who is still learning what matching means. Everything stores in the lidded keepsake box it arrives in, so nothing ends up under the sofa, and the box is handsome enough to give as it is.

The same Deep Sea artwork is printed on a child's umbrella whose sea creatures color in when it rains: Deep Sea Color Changing Umbrella.
