At You Spica glitter pens are made in Japan by the same company that produces the world-famous Copic markers! They are just as amazing as the Copic range and are an essential tool for any paper-crafter, professional or hobbyist! Each At You Spica glitter pen has acid-free, archival quality, non toxic ink. The ink is water-based pigment ink in which are suspended thousands of tiny micro-glass flakes! This combination, and high quality of materials used, gives maximum sparkle from your glitter pen!
