GÜTERMANN thread storage boxes keep spools sorted and protected so you can build and transport a colour selection neatly. The clear plastic case is sized to store up to 26 spools of the 100m thread size, making colours easy to identify at a glance. Use it for cotton or polyester spools, and close the lid before travel to help prevent shifting in transit Store in a dry place between uses Keep out of reach of children when not in use.
