The set of 48-piece Chameleon finellers comes with a unique system for sucking colors into each other. The ink is classically contained in the body of the liners, but in addition, the same color is part of the lid of the liners. The lids are freely compatible with all other liners in the set. Thanks to this, it is possible to mix colors indefinitely. All you have to do is put the lid of the desired color on the liner's body and the paint from the lid is sucked into the tip of the body.
