Copic Sketch 6pc set, Skin Tone (Discontinued)

Gifted this to my daughter and she is so pleased with it! She has been using them for two months and has nothing g negative to say. She loved this brand for her sketching, which she’s been doing for years now.

They are grate but when I used the copper it leaked out everywhere messing up everything I thought it my fault at first thinking I pressed down to hard so I redone it and well the same thing happened again.. I’m honestly not so sure about the copper it might have been me doing something wrong but just a warning?.. (the other ones did amazingly)
