For long-lasting, creative painting fun, you don't always need to buy a new paint set. The Pelikan replacement colors can be used in both the Pelikan paint sets K12 and K24, as well as in the Space+ and ProColor sets. So when your favorite color runs out, you can easily remove the color cup from the paint set and replace it with a new one. The replacement color Indian Yellow has strong opacity and lightfast pigments. The color cups are made from 95% recycled plastic.
