・For necklaces and long earrings with linked motifs, each jump ring is individually soldered. However, due to the manufacturing process, some jump rings may remain unsoldered.

The primitive invention of etching (Etching) dates back to around 1500 AD in Europe, where it is believed to have been first invented. Since then, it has been widely used in the creation of printing plates and works of art, as well as in the production of intaglio prints and electronic circuits, with a history of being applied to various metals, including copper. Today, etching is a widely used processing method in a range of industries, including semiconductors, electronic components, electrical parts, automobile parts, and medical devices.
