The combination of slightly rounded squared edges and a uniquely textured tip surface promotes positive ergonomics when in use – stimulating circulation and reducing tension. This is especially beneficial to those who may struggle with grip issues such as arthritis, etc. Not only does the surface of the Rocket² promote comfort while knitting, it also helps stitches stay on the needle – where they belong (think of it as a no-slip tip). And, thanks to the texture’s spacing, you will experience perfectly even stitches every time. Note: US sizes listed are per addi's packaging. When possible, please use metric measurements. Fixed circular needle measuring 40 cm / 16" tip to tip Available in sizes 2.0mm - 8mm (US 0 - 11) Made in Germany
