Made from the same high-quality beeswax as Stockmar"s crayons, these wonderfully chunky wax blocks are perfect for those who like to color outside the box. The block shape allows for different coloring possibilities, and also avoids the mess of a wrapper. Set comes in a handy reusable wooden box with a slide lid. Colors range in all shades of the rainbow and beyond. Stockmar products are certified nontoxic by the Art and Craft Materials Institute. Designed and made in Germany.
