Do you remember the legendary Game and Watch sets from Nintendo from years ago?. The ones which either had Donkey Kong or Mario on them. They were classic and cool and although the graphics were not much to talk about they were surprisingly cool at the time. Now you can buy these scaled down versions of game and watch titles in the form of a keyring and whatâ€™s better they actually work. You can relive them retro days with this very tiny Nintendo keyring. You may have to be a tiny mouse to work the control pad, but we donâ€™t care about that. Retro and cool and priced at only 9.99. Bargain and you can buy one here.
