Thank you for viewing. This is a transparent stone obi-dome (sash clip). It's an item that feels like it's from a certain era. It looks like crystal quartz, but I'm not an expert, so I'm not sure. Because it's clear, I think it can be used for casual to semi-formal occasions. There are some damages such as scratches on the surface, stains, and deterioration of the metal fittings. *Size: Length x Width... Approximately 19mm x Approximately 31mm Thickness... Approximately 14mm Inner diameter of the string passage... Approximately 9mm x Approximately 1.5mm *This item has been stored by an individual for a long period of time, so there is damage associated with aging. Please consider purchasing only if you understand that it is a used item. *The item is only the obi-dome. There are no accessories such as a box. Please note that recycled materials may be used for packaging. Anonymous shipping will be used.
