Pigmax + Macky set This is a set of twin-tip markers that can be used on glass and plastic, along with the familiar Macky. These were used by children and show considerable wear, but they still seem usable, so I'm offering them for sale. I've confirmed that all colors can be written with. Please check the images for wear, stains, and fading, and only purchase if you agree. - Model Name: Pigmax and Macky - Set Contents: Twin-tip - Features: Can be used on glass, plastic, metal, and paper They will be packaged carefully and shipped via post. If you have any questions, please comment. Thank you for looking. Sakura Cray-Pas Pigmax
