Prym Knit Pro Circular Knitting Needle Cord, 150mm, reference 223975 K, is a flexible cord that connects the needle points of the Knit Pro line, forming a complete circular needle. Prym is a German brand founded in 1530 in Aachen, the oldest family-owned industrial company in Germany, now based in Stolberg and recognized worldwide for needles, pins, buttons and sewing accessories. The interchangeable circular needle system allows combining different points with different cords, unlike a fixed circular needle of a single length. The 150mm length is a preferred option for knitting projects with a specific perimeter, such as hats, sleeves or larger garments.
