Roy Toy offers a collection of different building sets that are made in the USA. From their website:
Our wood log building sets are made from 100% USA materials, with food-grade dyes used to provide color. We lightly emboss the surfaces of each wooden block for a smooth finish that is comfortable for little hands. Our building sets can be configured in an unlimited number of ways, providing hours of imaginative play.
You can purchase Roy Toy Sets on Amazon.
