Tiny Tank Keyring

Tiny Tank is just one of Tokyo Bay Inc.'s collectible retro robot key chains.

Tiny Tank comes in blue, ivory or red (as pictured) and has a fully functioning clock built in.

His arms move, as well, and he measures about 1-3/4" tall. Tank's bigger "siblings" are portable alarm clocks with movable parts that are an homage to the original robot toys of the 1950s.
