An apparatus, system, and related methods for light reflection with grooved surfaces are provided. The light reflection apparatus with grooved surfaces has a first surface with a quantity of grooves therein. A second surface has a quantity of grooves therein. The grooves in the second surface have a different angular shape, different size, different angular orientation, or a different unit density than the grooves in the first surface. At least one light source emits light on the first and second surfaces. As a direction of the emitted light changes relative to the first and second surfaces, the quantity of grooves in the first or second surface reflect the light independently of one another.

Provided herein are identification collars or devices for a lifeguard. The identification collar and the identification device are generally unitary collars to which a plurality of reflective elements and a plurality of indicia are attached circumferentially on the outer surface of the collar so the wearer is easily identified from any direction. The unitary collars are made from stretchable elastic material.

A fashion item (100) including a thin wall with locally and selectively expandable areas including: an internal core (30) made of a lining material which can expand in contact with a liquid; a support layer (10) having an external face (11) opposite an internal face (12) on which the internal core (30) is arranged, the support layer (10) being configured so that the expansion of the lining material does not substantially cause its deformation; and an impermeable covering layer (20) attached to the support layer (10) so as to tightly enclose the internal core (30), the layer including one or a plurality of through holes (21) opening onto the internal core (30) and arranged relative to each other so as to form a predefined matrix, the covering layer (20) being configured such that the expansion of the lining material substantially causes its deformation.

The disclosed wedding ring necklace pendant includes the necklace, a retainer ring, the wedding ring the ring holder pendant, the pendant attachments, the retaining rod and the retaining rod rings.

Various designs also prevent an escape of the wedding ring from the pendant retainers including multiple loop retainers, hinges, rod bumps and enlargements.

A wearable jewelry includes a base member having a receiving chamber provided in a top portion thereof, a precious ornament and a rotation mechanism. The precious ornament element is provided with a mounting arrangement underneath, wherein the mounting arrangement is eccentrically provided with respect to the mass and shape of the ornament element. The rotatable mechanism includes a rotor body configured to be sited in the receiving chamber of the base member, a bearing device provided in the rotor body, and a rotor element rotatably mounted on the rotor body through the bearing device. The rotor element is affixed with the mounting arrangement of the ornament element so as to elevate and eccentrically mount the ornament element on top of the base member such that the ornament element is able to freely and smoothly rotate above the base member for any tangent force applied to the ornament element.

A bracelet defined by an elongated band having first and second terminal end sections that collectively define a clasp and a plurality of interconnected sockets extending along the length of the band and in each of which a rigid shell is positioned. A pair of charms each having unique indicia, such as a letter, imprinted thereon can be removably and interchangeably positioned within each shell. As an example of use, multiple friends' initials can therefore be displayed with charms positioned within each or many of the plurality of sockets forming bracelet.

A plate-shaped body portion curved in a thickness direction and having a back surface that abuts on a gum portion during the wearing is provided. The body portion has a thickness that is thick at a position where a first recessed portion to avoid an upper lip frenulum is provided or a portion adjacent to the first recessed portion and thins toward an end.

A sectional bra system and accessories includes bra and related jewelry components that can be interconnected in various ways. Jewelry items, such as bra straps, back bands, bridge, and other items, may be formed at least in part from alternating flexible chain segments and rigid connector segments with fasteners configured to attach to standard bra loops. Bra cups for sectional bras include various arrangements of standard bra loops allowing attachment of one or more bra straps, one or more back bands, a bridge, and alternatively other decorative items. Such bra cups may include standard bra loops along all edges. Coordinating jewelry may be made out of the same or similar types of components.

Provided is a 360-degree rotatable accessory. The 360 degree rotatable accessory can be used for various purposes such as a decoration of a bag, or a finger ring, a necklace, a bracelet, and an earring, can be rotated a predetermined angle, that is, 360 degrees around a coupling portion, that is, a body, and can be transformed into various shapes because it can be rotated a desired angle and firmly maintained at the angle, thereby having high commercial value and quality.
