The ChiaoGoo Quads Interchangeable tips 10cm (4 inch) are more comfortable to hold than traditional round needles, thanks to their flat sides and rounded corners.

The ChiaoGoo Quads Interchangeable tips are carefully calibrated to achieve the same gauge as round needles, so there’s no need to “size up” as with other brands. QUADS™ tips are compatible with all CG small [S] and large [L] interchangeable cables and are recommended for use with our NEW swivel adapters for an even more comfortable knitting experience.

Sizes US3 (3.25mm) – US 8 (5mm) have a SMALL [S] size join and work with any SMALL [S] diameter cables. 
Sizes US 9 (5.5mm) – US 11 (8mm) have a LARGE [L] size join and work with any LARGE [L] diameter cables.
