I just bought a set of nesting dolls. It looks great for the price. There is a "Made in Russia” sticker on the bottom of the largest doll. The doll opens with friction sounds. However, I added wax to the edges of each doll and now they open more easily and with less noise. I had to wash the wax several times; the wax is squeezed out. But I believe this fix works. Update: A 5-year-old Matryoshka recipient can open the entire set. This may be partly due to the wax. I thought it would be a bit difficult for me to open them without wax.
