The paint cups of the Connector Paint Box are arranged according to a playful, interlocking principle, like a jigsaw puzzle. The individual parts can be compactly interlinked for storage, or in various other ways while in use to inspire the child’s imagination and creativity. This in turn offers an educational benefit: paint cups connected together, for instance in the shape of a circle, promote the playful learning of colour relations or contrasts. Their relatively large base lends the individual paint cups stability, so they may be used on small desks as well. A removable, see-through lid, which also serves as a mixing pallet, allows for working with the templates printed underneath the lid and for coordinating colours accordingly.
