Provided is a button attachment tool that can eliminate or reduce rotation of a cap relative to an attachment tool body. A button attachment tool comprises a metal attachment tool body and a synthetic resin cap to which the attachment tool body is coupled. The attachment tool body includes a cylindrical part and a flange part extending radially outward from one axial end of the cylindrical part. The flange part includes a plurality of notches recessed radially inward from a peripheral edge of the flange part. The cap includes a clamping part that is fastened to a radially outer portion of the flange part including the plurality of notches.

A fastener element used to couple one or more items together, including layers of fabrics or other materials. The fastener element includes a top element having a central opening with a closed bottom surface adjoining a ring. On an underside of the ring is a protruding, piercing element that. The fastener element allows for more than two layers to be fastened together in a snap system and for a plurality of layers to be joined together. The fastener element can allow multiple layers to be joined together by coupling a first socket of a snap system to the top element and another socket to an underside of the ring and to the protruding piercing element. The fastener element can be used for multiple applications to secure more than one layer of fabric or another material together.

A magnetic fastener system has a first fastener structure with a body with a first side and a second side. At least one of a male or female friction-snap fastener is positioned on the first side. A pocket is formed within the second side and a magnet is positioned therein. A recessed surface is formed in an interior of the pocket. A captive wall is formed around the recessed surface. The magnet is positioned between the first side and the recessed surface. A second fastener structure has a shape defined by an outer sidewall, wherein the shape of the outer sidewall substantially matches a shape defined by the captive wall, wherein second fastener structure is removably insertable into the pocket, and the first and second fastener structures are magnetically connectable. At least a third fastener structure is removably connectable to at least one of the male or the female friction-snap fastener.

Provided is a snap button including a male snap button (30) made of metal and a female snap button (10). The male snap button (30) includes a base portion (31) and an engaging protuberance (32) which projects from the base portion (31). The female snap button (10) includes: a ring member (20, 120) made of soft resin, defining an engagement space (20a) which detachably accepts the engaging protuberance (32); and a female snap body (11) made of metal, accommodating the ring member (20, 120). The ring member (20, 120) is provided with a protruding portion (24) which projects further out to one side than an end (12a), on said one side, of the female snap body (11) facing the male snap button (30) in an axial direction, and which is provided in circumferential direction.

An ornament stud for an article is provided. The stud includes: a head having a three-dimensional shape; a plurality of shoulders extending horizontally and inwardly from an edge of the head by a predetermined length; and a plurality of sharpened extensions extending respectively and vertically from inner edges of the plurality of shoulders, the plurality of sharpened extensions being spaced from each other along the inner edges of the plurality of shoulders by a predetermined distance.

A pressure snap fastener with a bivalent closure comprises a first portion, to be associated with a first flap, and a second portion, to be associated to a second flap; where the portions, as associated with one another join the flaps. The pressure snap fastener further includes first temporary engagement means providing a temporary closure, in which the two portions are joined by a weakly joining and are free of partially swinging, and include second stable engagement means, providing a stable closure, in which the two portions are tightly coupled.

Provided is a snap button including a male snap button (30) made of metal and a female snap button (10). The male snap button (30) includes a base portion (31) and an engaging protuberance (32) which projects from the base portion (31).
