Made from sustainable, domestically grown hard maple and manufactured by a company-owned facility in St. Paul, Minn., these shape sorters come in two styles. One has two same-sized posts that slide through a large unit block; the other features the base unit with two sunken wells to fit differently-sized posts for matching. Both are natural wood with no surface finishes or coatings and smooth-sanded edges that are safe and comfortable for baby. Both sets can be integrated into a larger set of Beka unit blocks later for added play value.
