Shank hook button is a clothing button with a small loop on the back instead of a hole. The raised shank is the part of the button that allows us to sew the button securely to the fabric or clothing. The shank can be made of metal, such as zinc alloy or brass. They can be used to decorate any garment, especially shirts, coats, and blouses. They are durable and weather-resistant, making them perfect for home decoration, quick repairs, replacements, sewing, etc. The shank attachment on the back makes sewing easier.
