addi FlipStix are unique among double pointed knitting needles. One end of each needle has an extremely pointed tip, while the other is slightly blunter. This means that with the same set of needles you can choose to use the pointed end for pattern involving a lot of fine stitch manipulation, or you might use the blunter end when working with yarn that is prone to splitting. Whatever your preference, these colorful, aluminum needles are the perfect choice. The longer, eight inch length is ideal for larger circumferences such as sweater sleeves or hats. Each needle has the size printed on it, and they come in sets of five to accommodate working in the round on either four or five needles.
