This is the first edition of the 4-color combination percentage specification color guide (10, 11, 12). Some chips have been cut out and used, but there are still plenty remaining, so you can use them. There is almost no fading or discoloration, but there is a small stain on part of 10. Please check the photos. Also, the case is made of plastic, so please be aware that there are signs of use such as small scratches. I will ship it promptly, so thank you very much.
