Opaline apothecary jars

These apothecary jars were in my grandparents' garage, there are 4 of them, different sizes, 12.50 cm for the smallest, then 14.50, then 17.50 cm and finally 21.50 cm high for the largest. It is a belgian manufacture, they seem to be made of glass or opaline. They close tightly.
