SmartStix are knitting needles and tape measure in one; Marked at 1" intervals on both the needles and the cords, SmartStix helps knitters measure their creations on the go (while removing the need to use a tape measure), check their gauge and even test the yarn weight 
Every cord is color-coded making it easier for knitters to find the exact size they need; these needles are made from high quality, lightweight and ultra-pliable vinyl that is easy on the hands
