This is a nifty little gadget from Addi.
It is a needle gauge which measures needles in mms. There is also a measure in centimeters along one edge. On the reverse there is a blade which you can slide out - very useful for cutting yarn! The blade is retractable and safe to use.
The whole thing is not as big as a cigarette packet and so is easy to take around with you.
