Treble Clef is a custom deck of playing cards inspired by classical music. Originally, John Yohan Cho was working on this deck of playing cards. However, he suddenly stopped working on it due to his personal reasons. So I kindly asked him for permission to finish up what he had left. I decided to design the faces of the cards. In addition, I began to fix and add my ideas onto the back of the cards. Finally, it's ready to come out to the world! Treble Clef deck of Playing cards is functional. All 52 cards are fully marked with suits and values. If you are a magician, then you would be able to find your spectator's card without seeing the face of the card. Also, this deck contains two gaff cards that are very practical and usable.

This is the unlimited version of Treble Clef card deck in black. Treble Clef V1: Red and V2: Blue were 1000 decks limited edition and these were fully marked with both suits and values. This black version is an unlimited version and there is no marking system, but the design is still elegant and inexpensive, compared to the other two versions.
