Solder your own jewelry or create a unique jewelry set as a gift! A simple soldering kit with colorful color-changing LEDs that requires a little skill and a delicate touch. The kit includes accessories to solder 2 earrings and one pendant, each with 4 LEDs. The four LEDs are connected so that you can clamp a 3 V coin cell (not included) between the leads, and the LEDs will light up in all the colors of the rainbow. Included: 12 colorful color-changing LEDs 2 earring hooks made of 925 sterling silver 3 large steel rings, 12 mm 1 small jump ring, 4 mm Manufacturer and product safety information The earring hooks are made of 925 sterling silver, lead-free and nickel-free. Nickel and lead cannot be ruled out in the remaining parts of the kit. If you notice signs of an allergic reaction, remove the jewelry immediately and consult a doctor. Not suitable for children under 14 years of age or for persons who tend to put non-edible objects in their mouth. Always store all individual parts as well as the finished jewelry, especially the coin cell, safely and out of reach of children! Check regularly that the coin cell is still held securely in the jewelry to prevent it from being lost. Do not wear the jewelry in the presence of children, and keep the jewelry — especially the coin cell — out of children’s reach. Swallowing a coin cell is life-threatening. If ingestion or insertion is suspected, seek medical attention immediately. Avoid contact with water, perfume, hairspray, and cleaning agents to prevent discoloration. Please remove your jewelry before sleeping, swimming, or physically strenuous activities. Do not wear the jewelry during sports activities to avoid snagging. Silver jewelry may tarnish over time; this is a natural chemical reaction and not a quality defect.
