The plastic plate is used to determine the size of the knitting needle by test: if the crochet hook or knitting needle goes into the hole and there is no space between the gauge and the needle, the needle is the size of the number written next to the hole. The plate has 20 places between 1.5 and 10mm. In addition to these, there is a 50mm scale and a small cutter attached to this measuring tool.Size: 6x6cmMaterial:plastic
