A velvet bag with a large plastic bolt and nut hidden inside it. The child needs to feel for the nut and bolt, orient them correctly, and then to screw the bolt and nut using only his sense of touch. The Nut and Bolt Puzzle is great for concentration, manipulative hand use, and problem solving. A lovely tool for addressing praxis and tactile difficulties.

Size: Each velvet bag measures approximately 15 cm x 12 cm. The bolt measures approximately 6cm in length and the nut has a diameter of 4.5cm
