Keep your go-to Copic colors in rotation with Copic Ink Refills. Made with the same premium alcohol-based dye ink used in Copic Sketch, Ciao, and Classic markers, every refill is precisely matched to Copic’s complete 358-color system.

One 12 ml bottle goes a long way, refilling a Ciao marker approximately 9 times, a Sketch marker 7 times, or a Classic marker 5 times. The long nozzle delivers clean, controlled fills, and the clear barrel’s 1 ml markings help you track ink levels and avoid overfilling. Color-coded caps make it easy to find the shade you need fast.

Refresh dry or fading markers, mix custom colors, or apply ink directly for alcohol ink techniques. For best results, Copic recommends refilling gradually to help prevent leaks and protect marker performance.
