Handmade cloisonné flower pin brooch. This is an original piece, made by cutting and hammering a pure copper plate into a 3D shape. It utilizes the silver-lined cloisonné technique, incorporating silver wire and silver foil. The piece was meticulously crafted through approximately 10 firings. Size: Approximately 4cm x 4cm. The pin clasp on the back is a domestically-made pin brooch. The back uses a mixed black glaze, which is not completely black. The item will be wrapped in bubble wrap and shipped via non-standard mail. Please note that Japan Post does not deliver regular mail on Saturdays, Sundays, and national holidays. Delivery times may be longer than usual. Even if shipped on Wednesday, delivery may not be possible by Friday for distant locations, and delivery may be delayed until the following week. Each piece is unique. The colors vary slightly each time due to firing temperature and glaze thickness. There may be some color unevenness. There may also be traces of the kiln on the back. Please consider purchasing with an understanding of handmade items. Thank you very much.
