Play; using one's senses (site, touch, and sound) to interact with an object while experiencing the changes in light and shadow, proportion and rhythm, depth of field, etc. The objective for Naef toys is to produce play objects that unify quality design and superior Swiss craftsmanship. This has been their focus for more than 50 years and will remain the goal well into the future. Naef demands extreme precision and quality in the manufacturing of their Swiss Made objects. Each product is inspected by hand . Naef quality products begin by specifically selecting woods that will not shrink or warp and will remain durable over time. All of the painted products are made using non-toxic varnishes or clear coats. All woods are harvested from sustainable forests in Europe.
