Abstract: An attachment device or replacement button device for mounting on at least one piece of pliant material includes a carrier member having a carrier head and a carrier shank extending outwardly from the carrier head. The carrier shank includes a piercing point and a joining region exists between the carrier head and the carrier shank with the joining region having a curved portion with a predefined radius. A receiver is provided for receiving the carrier shank and retaining the carrier member in a mated relationship with the receiver. The receiver includes a smooth receiver head for non-abrasive contact with a user and a receiver shank extends outwardly from the receiver head to define a receiving well for receipt of the carrier shank. The devices are mated by a friction fit and the receiver shank length combines with the carrier shank length to provide a predetermined spacing between the carrier head and the receiver head to allow the device to be operated in the manner of a conventional button.
