Luke's Toy Factory's award-winning, eco-friendly toys are made in the USA with sawdust reclaimed from furniture manufacturers. By incorporating sawdust, they are able to use 30% less plastic than traditional plastic toys, and instead of being incinerated the sawdust is given a second life, resulting in durable toys with a silky-smooth feel. Toys are designed be 3D stacking puzzles with parts that mix and match. Slight wiggle room means that kids aged three and up, can develop their problem solving, creative play, and fine-motor skills without getting frustrated.
