A knitting needle and ruler in one?! Dang! That's Smart! Jimmy's SmartStix Double Pointed Needles are color coded (pink!) at one inch intervals, so you can measure your creations on the go... Heck, you can even measure your gauge and do wraps per inch if you want! Each needle is 5 inches long and made from high quality & lightweight aluminum that is easy on the hands. There are 5 needles per set.
