This is a set of rounded antique parts purchased from Kiwa Seisakujo. Please note that they are not for individual sale. All of them have holes. The parts to the right of the yellow measuring tape in the photo were given to me, while those on the left were purchased from Kiwa Seisakujo. Of the gold ball parts, 4 out of 10 have been used, so there are only 6 remaining. They were stored in a case like the one in the last photo. I will ship them via Mercari delivery.
