Good things come in small packages - and that is oh so true in the case of this Chromatix Building Block Set. This 19-piece set gets its name from the variations of colors along the chromatic plane. Designed to build eight equally sized cubes, measuring 1.6" per side, but fear not, that is not the only form this set can make! Included in the sturdy storage box is ten double sided template cards with three degrees of difficulty to show the breadth of building possibilities to the child! Chromatix Building Blocks are designed and manufactured in Germany. The blocks are made from sustainably forested Beech wood, and finished with water-based, solvent-free stains making these builders beautiful and safe. The geometric forms help to develop spatial understanding, challenge and grow problem solving skills, balance skills and strengthen fine motor skills through the medium of play. Great for a Block Play area or STEAM section of your classroom. The blocks can be wiped clean with diluted vinegar and water solution and a soft, damp cloth. The Chromatix Building Blocks are an ideal addition to classrooms, preschools, and the home environment. This product is recommended for children ages 3 yrs. +.
