Thank you very much for viewing my items on Mercari. Please be aware that there are many individuals and fraudulent websites that are illegally re-posting and falsely listing items from Mercari sellers. This item is an antique, detailed, copper alloy shachihoko (dolphin-shaped ornament) from the Edo period, of unknown origin, and is a period decorative fitting. It is unknown whether this was originally used for weaponry or as part of a building, so please be aware of this. I believe it is approximately 200 to 350 years old. The appearance and texture give a sense of being a decorative fitting of a high-ranking samurai family from that era... For reference, the dimensions of the item are approximately 17 cm in length, 13 cm in height, and 5 cm in thickness. It also weighs a considerable 385 grams. If you are interested in or have an interest in such Edo period samurai era shachihoko decorative fittings, I hope you will take this opportunity to feel its wonderful atmosphere in your collection, so please consider it. Please note that this is a very old item, so please understand the nature of antiques regarding its condition, and appreciate it as evidence of its age.
