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