Annansilmät products are made by the visually impaired in Finland. The wood components of the products are usually Finnish birch, alder or willow. Most of the wood in the brushes have been oil treated. Laudeharja (for Sauna seats) has tar treatment that protects the wood and leaves a pleasant smell of tar in the brush. All products have a Finnish key symbol that strengthens the competence and quality of Finnish work and tells about the authenticity of the material. Handmade products are all individuals, so there may be differences between products.
All brushes should be set to dry the bristles downwards, allowing the wood part to breathe through the holes.
