It is a part of the formosome that has a circular lump.
The hole size is about 1.6mm.I'd like to use a part in a canui to connect to it.It's very light, so you can also recommend an accessory on which you have a volume. * In the manufacturing process, the white portion (the rest of the polishing agent) is found in the rare shape, but it is easily removed by the fingernails.In addition, if there is a hole, it can be easily removed by a eyed or a like. * There are cases where there is a mark of white on the top of the object.Please be careful.
