Check out this deck of cards from Mikol. You might remember this company from their marble notebook that I reviewed almost 2 years ago. Now they are back with a deck of playing cards that are made of marble. Yes, stone playing cards. They are the same thickness as a credit card and feature laser etched graphics. Although the price for a deck of these cards would probably make any buyer resist actually playing with them, the cards are durable and can be dropped without breaking. $775 though. OUCH. Still interested in adding a deck to your collection? Head over to Mikol for all the details.
