Tulip Clear Quick Gauge is a transparent square gauge ruler that easily measures the number of stitches.  Simply place the helpful little tool over your knitted or crocheted piece and count the stitches. 

The inner circumference of the ruler measures 2 inches/5cm, the outer circumference measures 4 inches/10cm.

The yellow coloured scale is visible on both dark and light knits, making it the perfect gauge.
