This is 1 oz of 21.5 micron citron green merino wool roving. It's great for Nuno Felting, Needle Felting, Wet Felting, Spinning, and other fiber arts. This color is extremely bright and is almost neon. I've tried to get as close as possible to the true color of the fiber , but all computer monitors display color differently. Please keep that in mind when placing your order..
