Knitter's Pride Cubics Knitting Needles (4 sided) are made in Symfonie, a densified laminated wood that’s harder than either ebony or rosewood. Cubics won’t absorb water like other wooden needles which means there’s no chance of warping and allows for sharp tips giving you a lifetime of pleasurable use, if handled correctly. Please remember that all wooden needles in the lower ranges (2.0mm-3.5mm) should be treated with appropriate care.
