Ocamora nesting arches are made in Spain with linden wood harvested from Spain and France. The wood is labeled with FSC certificates and the arches are treated with ecological and environmentally friendly products. The oils that are used to finish the Ocamora toys are a mixture of flax oil, tung and some vegetable oils. The stains that are used to colour the wood are made from water dyes. Both the oils and stains comply with the safety regulations for toys.
