# Pre-drilled Parts ↑ Click here for other pre-drilled parts I drill holes in sea glass collected from the Sea of Japan side of Yamaguchi Prefecture and polish them with cream and oil. ・I drill holes when I have time, so I can't prepare a large quantity immediately. ・I cannot accept any processing of shapes other than drilling holes. Please refer to the grid for the size. If you wish to purchase with other products, I will create a combined page, so please comment before purchasing.
