Knitting needles in a variety of sizes (US 2, 4, 5, 6, 7, 8, 9, 10, 11, 13 and 15 from the bottom). The US size 7 and 15 needles are bamboo and wood, respectively, whereas the others are aluminum. Having a smoother surface, metal needles tend to produce faster knitting but stitches are more likely to slide off by accident.
