My 4 year old daughter loved the “project box” from Koala Crate. The contents and art projects were thoughtfully planned out in order to use all of the supplies to make suggested projects. It comes with supplies to complete three projects: an apron that the kids can decorate and then use throughout the rest of the projects, an abstract art canvas painting project, and then a marble rolling/painting project that finishes into a sculpture. The materials in the art box were all great quality and I enjoyed how the box itself became part of the project (for use with the marble painting). My daughter really enjoyed the marble painting and is now using the materials to make more fun artwork. This box has everything needed in order to complete multiple projects with step by step instructions.
