Work at your own pace and interact with your acrylic paint! With a longer hardening time of five to seven days, Atelier Interactive Professional Artists' Acrylic Paints stay wet on the palette and don't form a skin, allowing users to beat and rework the different layers of paint. Plus, the paint can be continued to handled even after it is touch-dry - simply restore moisture with a spray mist and continue to interact with the paint. These intense colors are useful and light with minimal color change once dry. This Starter Set includes twelve 20ml tubes of Atelier Interactive Professional Artists' Acrylic Paint, one color chart, a mediums guide and a CD-ROM guide voucher.
