This JOVI range is called Multicultural colors: six sticks of plasticine of 15 g each in a card wallet, in six skin tones running from very light to dark brown.
The idea behind it is simple. A child modelling a figure or a face can pick the tone that matches their own, or a brother, a sister or a classmate, instead of settling for one standard colour. The tones also mix with one another, so it never stays at six.
Plasticine is soft, oil-based modelling clay that does not dry out: a figure can always go flat and start again. It kneads easily, and rolling, flattening and poking take no great strength.
The packaging states from 2 years. An affordable little gift and a welcome top-up for the craft box.
