Price change on March 11: 5,500 yen → 4,990 yen --------------------------------------------------- This is a set of two 28mm screw shafts. You can attach separately sold plates to use them as dumbbells. The total length is 40cm. I used them for a few years, but always used them alone at home with gloves, so they are not as dirty as items used in a gym. There is no significant rust from sweat on the knurled grip area in particular. - Brand: BODYMAKER - Size: Hole diameter 28mm
