Sopo's new product, Perinteinen Pihkasalva30%, has received the prestigious Avainlippu symbol, which indicates its Finnish origin.

Traditional Pihkasalva 30% is made from 100% Finnish raw materials. The development work and the cardboard package were also done in Finland. The use of resin is also a part of Finnish tradition: resin has been used to treat wounds in Finland for hundreds of years.
