The ruler/needle meter is made of wood and is a useful tool.
It often happens over time, that the indication of the size on the needles are no longer legible, and this is when the caliber is really indispensable. Just insert a tip into the measuring slots and you will immediately know the size. The gauge is suitable for measuring knitting needles from size 2.00 to 10.00 mm.
Needle meter on the one hand, and ruler on the other. An indispensable accessory.
