Addi Rocket Squared, 16" circular needle: US 4 (3.5mm)
Addi Rocket Squared is a square needle with a textured surface that promotes better ergonomics, stimulating circulation and reducing tension. The slight ridges on the surface of the needle allows you to grip with less effort, and it also holds the stitches on the needle better. The slick and tapered tip allows the stitches to slip of the end when you want them to. Styled after the popular Addi Turbo Rocket, these sharper tips are plated with the same shiny nickel that gives the classic addi Turbo its incomparable zip.
This 16" length is widely used for child and adult hats, baby cardigans, sweater collars and other projects with a medium circumference.
