The knitting needle gauge's precise holes are laser cut from alder hardwood, an American hardwood. These are perfect for measuring knitting needles from sizes 0 to 17. Both the US sizes and metric measurement are clearly etched above and below each hole to ensure it is universal for every knitter. Each piece is hand sanded after laser cutting to smooth out corners and edges.
Each of these needle gauges measure approximately 2" x 4" x 1/8". Because it is made of a natural material, the appearance of each item may slightly vary.
