The Knitter's Pride Cubics line consists of fixed circulars, single pointed needles, and double pointed needles. Each needle is marked with the size, which makes finding the needle you're looking for a quick and easy task. They are made of densified laminated birch wood which is more costly and much harder than either ebony or rosewood. The Cubics line of needles is square in shape and fits nicely between your fingers, similar to a flat sided pencil.
