They are durable, resistant to corrosion, and will not bend or break under finger pressure. [Widely used] 18 detachable buttons of different styles are used for jeans and rivets, shorts, backpacks, hats, suits, pants, jackets, shirts, sweaters, belts, etc. There is no need to sew. When your pants are not suitable for jeans, buttons will make loose jeans smaller, and instantly extend or reduce the waist circumference of the pants. [Card slot design] The button has a unique card slot design, which will not fall off when stuck, and will be as tight as a card for a long time. The ingenious built-in spring makes the button have a detachable precision structure. It is also an excellent substitute for missing buttons.
