Made of a strong semitransparent plastic, it contains 18 horizontally positioned spools. This is the best solution in order to easily find the right color for the pattern. Its practical cover hinged to the structure, and its excellent closing make this combo box one of very easy storage. Accidental opening during storage or transportation are thus avoided. Since Box 18 can also be used to contain small parts and accessories - such as beads, hooks and so on - it proves to be an extremely useful accessory to keep close at hand.
