Beading Needles - Size 15These are some of our thinnest beading needles. These needles are 1. 75" long. These needles generally work with Nymo size OO. Often referred to by beaders as "longs, these stiff needles are very long and fine, making them perfect for passing through rows of beads or even embroidery projects. These needles can be purchased either in a package of 25 needles or a package of 5 needles. (These needle prices have unfortunately increased due to tariffs.)
