Vintage Italian Box of 12 Wooden Spools x 100m Grey Blue Thread

12 wooden spools of 100m each of  strong grey/blue cotton thread.

The wooden spools measure 4.cm tall by 3cm wide.
I've taken the protective cover of one spool so you can see the colour.

I found these in an old Haberdashery Warehouse I cleared and they were originally made in Italy.
