This is a set of 24 Copic markers. I purchased them about 7 years ago. I have confirmed that all of them still work. The cool gray colors show some use, but some are almost unused. I have wiped down the case, but please understand that these have been stored by a private individual. - Colors: B14, B29, B32, B37, B39, V09, R08, YR04, Y13, YG03, G17, RV11, C1, C3, C5, C7, C9, W1, W3, W5, W7, W9, 100, 110 Copic
