This circular needle set has a case for easy selection and storage of needles and cables. Set includes 12 tips sizes Us 3-15 as well as 5 cables in the following lengths - 16”, 24”, 29”, 36” & 48”. The needle tips are 4 inches (3, 4, 5, 6, 7, 8, 9, 10, 10.5, 11, 13, 15) and have a shaped tapered tip and silky finish so no drag on your project. The joins are smooth and stitches slide easily. I enjoy the bamboo needles as they are strong and smooth and easy on your hands versus metal needles. This is a smoke free and pet free home.
