MOP (mother of pearl) is one of the best quality of clothing buttons choices on the market. Because it is made of the inner layer of pearl oysters, it carries the colour of the real pearl. With a great resistance against wash and clean, it becomes a classic favourite detail for many high-quality shirts.
How to identify a MOP button?
First, MOP buttons always carry a rainbow shine while you change your viewing angle. Second, MOP buttons always look well-polished on front and back. Third, MOP buttons are always much cooler to the touch, compared to the plastic ones.
