I am selling these because I bought them but haven't used them. I'm not sure about the colors, but it looks like I drew lines with them for testing, maybe once or twice. This is a type that can write both thick and thin lines with one pen. 【Convenient Storage Case】 A dedicated storage case is included, making it easy to carry and organize. - Number of colors: 60 - Storage case: Yes - Type: Marker I will ship the pens in a Yu-Packet Plus envelope, with the pens taken out of the case and placed in a transparent packing bag to prevent water damage. Due to the thickness, the case will be folded and placed in the envelope without being put in a bag. #nodaya
