Pro Takumi bamboo is sustainable, polished to perfection and has an exceptional feel. They feature color-coded tips for each cord length for quick visual identification. The cords also rotate and will not get twisted, allowing you to carry on knitting unhindered. The careful polishing process creates a smooth surface and natural texture for an ideal glide without your work slipping out. The engraving on the bamboo is delicately etched, resulting in a smoother surface that ensures uninterrupted yarn gliding.
