All Nina Ottoson toys are made in Sweden, a country known for its environmental consciousness, and Ottosson is proud that her toys are as environmentally friendly as possible. The wood comes from timber that cannot be otherwise used, and the non-wooden parts are made from recycled plastic mixed with the fine sawdust that's a manufacturing byproduct of the wooden sections. And, as is common in Sweden, at the end of their useful lives, the toys can be left at recycling stations so the materials can be reused.
