# Pre-drilled Parts ↑ Click here for other pre-drilled parts Sea glass collected from the Sea of Japan side of Yamaguchi Prefecture, drilled and polished with cream and oil. * Drilling is done in my spare time, so I can't prepare a large quantity immediately. * I cannot accept requests for shaping or other processing besides drilling. Please refer to the grid for the size. If you wish to purchase with other items, I will create a combined listing, so please comment before purchasing.
