“The four of Woolga” is a lovingly designed wool sock packaging for the whole family. The product set contains four boxes, each with an illustration of a particular family member: father, mother, child and baby. The mother of the family, called Woolanka, was sent to customers together with a letter. If a customer replied online, he received the whole family during winter sale. The four boxes can be placed one inside the other like the Russian Matryoshka dolls and encourage buying and collecting.
