Grimm's Concave Finds Convex


A quite tricky and challenging building game in which two parts must be found! Make it more difficult by feeling the counter part under a cloth. It playfully promotes the sense of form, the strategy of searching, and observation and matching skills. Because the different shapes always result in new figures, the individual blocks are ideal for playing outdoors and for imaginative play.
