This wonderful kit invites kids to get creative with rocks! When children decorate the rocks, they can hide them outdoors to spread kindness, encouragement and happiness throughout the community—one rock at a time. Kit includes 10 natural river rocks, 8 weather-resistant paints, 2 paintbrushes, a transfer sponge, more than 30 waterproof transfer designs and 4 gold metallic transfers. Rocks vary in size and weight. Packaging may vary.
