OBNDO Children''s checkers / toys

OBNDO Children''s checkers

Chinese traditional mortises and tenons are shown in different fields. Toys are one of the mortise and tenon applications. Moreover, mortise and tenon have mutability and logicality, which has a good application prospect in the field of inquiry learning. By integrating the traditional mortise and tenon building blocks in China, we hope that children can use OBNDO to build a basic board and create a new type of game. On the one hand, the traditional mortise and tenon culture can be promoted; on the other hand, children's creativity and spatial imagination can be developed. We hope to create a lego empire with Chinese characteristics.
