Decorate light, dark, or colorful paper as well as smooth surfaces like plastic, foil, porcelain, glass, and metal with a high-quality metallic effect. You can even make wood or rocks look shiny. Once dry, the metallics are both smudge-proof and splash-proof. They can even be made waterproof (not dishwasher-safe) by placing them in an oven at 160°C for 30 minutes. The special water-based metallic ink is odorless and does not bleed through the paper. Additionally, no pumping or shaking is required.
