With these mats, children can build up a colorful house of cards (much easier than with cards because the surface is more rough) and begin to develop a sense of color harmony, too. The mats are a wonderful addition to our building block sets to construct towers and buildings with colorful stairs, windows, balconies and floors. 40 plates in a wooden box. 20 color pairs.
Materials: ply wood, non-toxic water based color stain.
