Engage your kids with an unusually cool and creative game. Guidecraft has come up with a smart gaming challenge for kids with its Screw Block. The Block set is suitable for kids aged 3 years and over. These smooth edged wooden blocks are safe, free from toxins, and are eco-friendly! With an eye-catching design and smart color variations, the Block Toy can keep the children engaged for hours. The Screw Block set includes wooden blocks and small screw-shaped blocks along with a single screwdriver-like block. The screwdriver block is safe—you can place it in a dedicated nylon interior after the day's play. Screwing/ unscrewing these blocks employs hand-eye coordination—critical for young children. This Block Game’s standard measurement reads 4" W x 4" D x 6" H.
