Bamboo crochet hooks are very lightweight, and have a warm feel for long crochet sessions with less hand fatigue. All of our needles feature laser engraved sizing (in mm) for easy identification. The shafts of our needles are perfectly round with uniform thickness within each size. The hook points are well formed with a smooth rounded taper, and slightly blunted tips to prevent splitting yarns.For best results, before using, and between each project, rub the hook briskly with a piece of wax paper. This will put a little bit of wax onto the bamboo, sealing the grain and making them even smoother to work with.We"re confident that you"ll be pleased with these crochet hooks, so we offer a 30 day money back guarantee, and a 3 year free replacement guarantee. If you ever break a needle, just send us a picture, and we"ll get a replacement out to you for just the cost of shipping.
