The fagus combifix system is unique in its form, function and variety. Due to the large variety of possible combinations a child's fantasy and creativity are stimulated. By combining different combifix sets even more combinations are possible, and the square grid design on the base plates allows for near unlimited connection options. Combifix is perfect for small children because it does not contain any small pieces. It is suitable for children starting at age 1.5, but we recommend it for children starting age 3.
