This is a Bullworker 2 exercise device. It appears to be used for muscle training by applying force from both sides. There is some deterioration, stains, and dirt, but it also comes with a case. The condition of the case is not very good. I tried moving the device a few times, and it expanded and contracted without any problems. There are signs of aging, such as small scratches and surface rust on the metal parts, but considering its age, it seems to be in relatively good condition. - Model Name: Bullworker 2 - Type: Expander
