Kollage Square needles are high-quality, aluminum needles made in North America. Many find that the square shape is easier on the hands, making them ideal for those suffering from arthritis or other painful conditions. Some people also notice that using square needles helps make their stitches more regular and even. The size is engraved right on the side of the needle for easy reference. Five needles come in a set to accommodate working in the round with either four or five needles. The five-inch length is compact and convenient.
