This amazing toy is a 3-D puzzle, sorter, and pull toy, all in one! Children can reassemble the train by matching the pieces according to corresponding shapes. When it is all built back up, kids can use it as a pull toy. This hardwood pull toy is beautifully crafted, and will stand up to years and years of play. Rubberwood is used to make toys that are bright, colorful and are good for the environment. In the past, rubber trees that were no longer producing latex would be burned. Now, these abandoned trees are utilized to make sustainable playthings.
