Stoelzle Masnieres Parfumerie, based in northern France, plans to increase its production capacity.
The perfume glassmaker will replace its existing furnace with a new, larger one in the summer of next year.
It means the group can also develop a fifth production line.
Etienne Gruyez, the facility’s CEO, said the investment would increase production capacity by 30% and create jobs in the Hauts de France region.
