Grimm's Spiel and Holz created this perfect first block set with their 100 piece Mosaic Square Building Set, which is well suited for developmental uses as it's aesthetic ones. Its subtle yet vibrant colors progress from pale yellow to deep purple and all 100 blocks are nestled comfortably in a wooden tray. This toy is ideal for early building games that foster teaching children about colors or simply as decoration in your home. Grimm's Spiel und Holz toys are lovingly designed and manufactured in Germany. Toymakers use only the highest quality, sustainably harvested wood and completely natural, non-toxic dyes, paints and finishes.
