A pendant for a necklace has a body with an aperture, and a hole extending into the body from the aperture. The hole terminates at a closed bottom in the body. A body coupling is adjacent the aperture. A lid can be attached to and detached from the body. The lid also can be mounted to the necklace to support the body therefrom. The lid has a lid coupling to couple to the body coupling to close the aperture. The lid coupling can be uncoupled from the body coupling to provide access to the hole. A container is removably mounted in the body. The container has a retained position where the container is in the hole in the body when the lid is mounted to the body. The container also has a released position with the lid detached such that the container is at least partially exposed from the body.

Multicolored flexible wearables include a first portion having a first flexible polymer forming a toroid and including one or more colorants, a first surface, a second surface, and a recess in the first surface not reaching the second surface. A second portion formed of a second flexible polymer fills a majority of the recess and includes one or more colorants. The first and second flexible polymers have different colors and are permanently bonded together. Precious material particles may be disposed within the first and/or second flexible polymers. One or more of the colorants may have a color matching a color of the precious material particles. One method of bonding the portions includes depositing a liquid second portion into the recess and then curing it. Another method includes depositing a solid second portion into the recess and then curing a liquid layer of polymer between the first portion and second portion.

An illuminable hair attachment assembly for providing remotely controlled illumination includes a hair attachment, which in turn comprises a shell. At least one face of the shell is substantially transparent. A bulb is engaged to the shell and is positioned in the shell. A fastener engaged to the shell can engage a lock of hair. The hair attachment is one of a plurality of hair attachments, at least one of which has a microprocessor, a battery, and a first transceiver engaged to and positioned in the shell. The microprocessor is operationally engaged to the battery and the first transceiver. The shells are selectively mutually couplable so that all the bulbs of mutually coupled hair attachments are operationally engaged to the microprocessor. Programming code positioned on an electronic device of a user and enables the electronic device to signal the microprocessor to selectively actuate the bulbs.

An apparatus for praying the rosary includes a flexible elongate member and a plurality of beads and transition objects carried thereby, a display fixedly attached to each of the transition objects, and a unitary structure that is connected to each end of the conductive wire bundle. The plurality of beads includes sets of beads separated by respective transition objects, wherein one portion of the flexible elongate member is a conductive wire bundle having a plurality of wires for providing power and ground for use by the transition objects. Each display includes a plurality of sections which are individually illuminated by a respective light source to reveal or visually highlight an image in the respective section. The plurality of wires is electrically connected to the display to provide power and ground to the respective light sources. The unitary structure houses a clock, a logic circuit, and a power source for the clock and logic circuit. The logic circuit is electrically connected to the conductive wire bundle so as to output power to one of the respective wires of the conductive wire bundle in accordance with a day of the week as determined by the current state of the clock, and thereby illuminate one of the plurality of sections in each of the transition objects.

The present invention provides an illuminated wristband having one or more removable and interchangeable attached LED lights. Specifically, in the first embodiment, the illuminated wristband preferably includes a hook and loop wristband having a first end, a second end, a top surface area and a bottom surface area. Also, in the first embodiment, the entire top surface area around the wristband has a loop portion. In the second embodiment, the illuminated wristband includes a hook and loop wristband having a first end, a second end, a top surface area, a bottom surface area, a first side surface area, and a second side surface area. Also, in the second embodiment, the entire first and second side surface areas, and the entire top surface area have a loop portion. Each of the LED lights has an outer housing having a hook portion so that each of the LED lights can be removably attached to any loop portion of the top surface area of the wristband in the first embodiment, and to any loop portion of the top surface area, and first and second side surface areas of the wristband, in the second embodiment. Further, each of the LED lights includes an outer housing containing one or more light emitting diodes, and a battery; and optionally includes a control circuit, and a button controller.

The claimed invention provides a new, stylish and useful way of layering necklace jewelry so as to avoid tangles between necklaces and to reduce the complication of untangling tangled necklaces.
