This is a color card necessary for the official text of the Color Coordination Examination. Although it's the old type, the necessary colors haven't changed, and the examination association has explicitly stated that there's no problem using this for studying for the exam. I am an instructor and carried it around to show to my students. It's unused, having only been taken out of the bag a few times. - Product Name: New Color Card 199a - Manufacturer: Nihon Shikiken Co., Ltd. - Color Variation: Multicolor - Size: Approximately 12cm x 3cm - Usage: Color sample, for design reference Thank you for looking.
