Addi Turbo Needles are arguably the fastest, slickest metal needles available! The Addi Click Interchangeable Needle System was one of the most anticipated products to come from Skacel and they did not disappoint! A unique locking mechanism holds the needle tips and cables together, making for a secure connection with no risk of detachment. All with Addi's signature smooth nickel coating. The kit includes 10 different sizes of addi Turbo tips (US 4 – US 15), three different lengths of addi's new, pliable blue cord (24”, 32” and 40”), and one connector piece which helps to either store stitches or combine your cords.
