This is a very nice card clip made from a durable clear plastic material that has a blue tint. It is laser cut, laser etched and handcrafted to ensure lasting quality and durability. 

Besides protecting your cards and keeping them from warping what is interesting about this clip is the blue tint. It is the same color as the tinted eyeglasses that card cheaters used to use to spot cards that were marked with daub or luminous ink. Have not tried to see if that works but it should. It can also be used to spot hidden information for mentalists. It is also shiny enough to be used as a shiner.

Manufactured by Magic Encarta the card clip features their logo on the front and the expression, “Impossible Is Nothing…” on the spine.
