Provided is a snap button in which a swaged portion of a to-be-swaged pin is not visible from users. The snap button comprises a snap button body and a cap to be connected to the snap button body with a cloth interposed between them. The snap button body includes a base; a pin to be swaged, which protrudes from an inner surface of the base, the inner surface being placed to face the cloth; and an engaging portion provided on an outer surface opposite to the inner surface of the base. The cap comprises a cap body including a cap base; and a metal eyelet attached to an inner surface of the cap base, the inner surface being placed to face the cloth. The eyelet comprises a cylindrical portion for receiving the pin which has pierced the cloth and swaging the pin on the inner surface of the cap base.

A fastener assembly that allows a user to change the appearance of a leather good such as clothing or an accessory by interchangeably attaching ornamentation to clothing or accessory, changing the appearance of the leather good. The fastener assembly is easy to use and only requires a user to place an ornament having an anchor attached over a base attached to a leather good and rotating to lock the ornament in place. The fastener assembly has a plurality of flanges on the anchor that prevent the ornament from rotating and falling off the base. A disk magnet inside the anchor further locks the ornament onto the base. The fastener assembly is useful for a wide variety of clothing and accessories made of leather or leather-like materials. The style of ornament is without limit.

A button mounting device includes: a button mounting unit that comprises a first die holding the button main body and a second die holding the button mounting tool; an intermediate material formation unit that forms an intermediate material, which is to be interposed between the button main body and the cloth or between the button mounting tool and the cloth, by cutting a strip-shaped sheet material; and an intermediate material transfer unit that transfers the intermediate material formed by the intermediate material formation unit to the button mounting unit to supply the first die or the second die.

A press stud comprises a male element and a female element, which show, when coupled, a capacity for mutual transverse displacement with respect to the coupling direction to move, when subjected to tension acting in a substantially transverse direction with respect to the coupling direction, from an uncouplable position to a locked position. An elastic centring member exerts an elastic force on the male element and/or on the female element to keep them in the uncouplable position in the absence of tension acting in a substantially transverse direction with respect to the coupling direction.
