This is a joyous rainbow stack of connected discs for identifying knitting needle sizes US 0-15 / 2-10 mm.
The discs swivel out and click back together with tiny magnets (which makes it as much fun to play with as use) and the whole rainbow tool is small enough to pop into the Accessory Roll so you'll never leave home without it.
Overall size (closed) is approximately 1" diameter X 1.5" high (2.5 cm X 4 cm)
Gauge clicks into place with tiny magnets embedded on the underside of each disc
The discs are made from 100% fiber waste called polylactic acid, which is made from fermented plant starch such as corn, beets or sugar cane. It is 100% biodegradable and contains no plastic.
