The addi Click Rocket - Long Tips are just over 5 inches in length. They are fully interchangeable with the addi Rocket Click - Short Tips and addi Click Cords and connectors. Keep in mind that because of their longer length, they will not produce a working needle with the 16 and 20 cords - Please note the Tip Packs only include additional knitting needle tips. Additional cords are sold separately. You can also view all Addi Rocket Click - Long Tips Needles.
