Wooden Deck Of Cards

A couple questions here on these wooden cards: How do you shuffle them? Couldn't you memorize the grains and shades of the wood on the aces? Splinters? When playing Go Fish can you ask "Do you have wood?", $200 for wood cards? Are you a complete imbecile? The wooden deck of cards features 52 wooden cards that are "works of art", plus jokers, and comes with a leather carrying case. I also wonder if they took the time to make a wooden instructions card...
