Glass Pen Set Immediate purchase OK, but please check profile. This is a set of a glass pen and 4 ink colors. You can enjoy a glass pen right away with this one set. The inks are yellow, pink, black, and blue, with a transparent feel and a pearlescent glitter-like substance. It has been opened to check the contents but is unused. However, the mouth and lid of the blue bottle were originally stained with ink (I have wiped them for this listing). Please check profile before commenting or purchasing.
