I purchased this at Ginza Itoya. It is a process color sample book from the Visual Design Laboratory. It uses color chips of about 30 colors out of 1024 colors, based on CMYK percentage combinations. Please understand that this is a used item that has been stored without use for a while. A visual color scale ideal for visual evaluation of colors. - Model: VICS 1024 - Type: Visual Color Scale - Color Samples: A, B, C, D, E, F, G, H - Application: Visual color evaluation - Package Contents: 4 sets of color sample cards Please take a look at my profile. I look forward to a smooth transaction with those who understand no cancellations and no returns.
