The clean lines and Scandinavian design of the Rento Pisara sauna products are purely the result of Finnish work. The Pisara products are manufactured from a completely Finnish biocomposite called UPM Formi*. The durable natural fibre composite is pleasant to the touch and an excellent choice of material for the heat and humidity of the sauna.

*UPM Formi, from renewable pulp fibres and clean plastic polymers. Recyclable, can be converted into energy by burning. The material have been manufactured in Finland.
