A total of 140 cylinders are elliptical. The circle has a diameter of about 11mm and is one of about 11mm yellowed, including about 6mm out of the inside of the twisted section. The secondary is the dirt that appears to be soil or sand on the surface, or some black spots on the rail. Because it was in the TOSO case, it is likely to be of TOSO. It will be taken out of the box and shipped flat. Please agree that you don't know about the parts. # curtain runner # curtain # curtain rail #DIY # parts
