Add more flexibility to your HiyaHiya Interchangeable Set with additional cables! Sock cables with lifeline holes are designed to fit HiyaHiya Interchangeable Needle tips size 2.00mm/US0 - 2.50mm/US1.5. Needle lengths are measured from tip to tip (for example, a 24"/26" cable is 17.5", in order to make the finished circular needle 24" or 26" long with 4" or 5" tips respectively). Cable color may vary. You can use a Sock/Small tip adapter to use 'Small' gauge tips with 'Sock' cables, available separately.
