An apparatus for selectively attaching and removing a golf towel from a golf bag, golf club, or other metal surface comprises a magnetic holder that can be inserted through an aperture formed in a golf towel or other similar object. The magnetic holder comprises a multi-part body with a threaded portion that connects two body portions where the threaded portion is configured be inserted through the aperture and secured in place via matching threads. The magnetic holder further comprises one or more ball marking devices that are magnetically attached to the magnetic holder, where the ball marking devices can be selectively detached from the magnetic holder and used to mark a desired golf ball location.

A retractable towel apparatus is disclosed. The retractable towel apparatus includes a plurality of retractable cord and clip modules, each formed of: a housing configured to house a retractable cord, and a clip, wherein the clip is coupled to the retractable cord. An adjustable bar is coupled to the plurality of retractable cord and clip modules, in some embodiments. Some embodiments include a pivoting portion on the clip coupled to the retractable cord.

A clip for removably and releasably securing an item onto a structure may include a singular, elongated body with an interior portion forming a cavity on the bottom end of the elongated body. The cavity may be sized and shaped to receive an edge of the structure for removably securing the clip to the structure. The clip may include a pushing surface sized and shaped for a user to removably secure the clip on the edge of the structure. The clip may also include a first set of two or more tabs disposed along the side portions of the elongated body and projected out at an acute angle, the first set of two or more tabs sized and shaped to provide a gripping surface on the side portions of the elongated body for the user to pull the clip off of the edge of the structure.

A vacuum retaining device capable of reuse includes a sucking disk member. The periphery of a disk surface portion of the sucking disk member is formed with a coupling edge portion wrapped and connected with a sealing rim. During use, the coupling edge portion inside the sealing rim forms a support, such that the shape and efficiency of the sealing rim can be kept for a long time. When a sealing surface of the sealing rim is poked to disengage from a surface to be adhered, the sealing surface is able to link the coupling edge portion of the sucking disk body. When the vacuum retaining device is not used, the outer edge of the sealing rim is poked for the air to enter the interior of the sucking disk body. The vacuum retaining device can be detached from the surface easily and conveniently.

A suction cup, including a bowl-shaped framework, a cup body covering the framework, a connecting rod on a back surface of the framework and passing through the cup body, a bowl-shaped cup cover placed on the connection rod and covering the back surface of the cup body, and an annular protruding rib placed on the periphery of the back surface of the framework, which is in direct contact with the inner surface of the cup cover for effectively transfer the pressing force to make the suction cup less likely to fall off from the supporting surface.
