Oyster Worker is an oyster farmer’s work chair made of oyster shell materials. In the process of oyster farming, the oyster farmer can drill holes in the oyster shell and pry open the oyster shell through the manual structure device on the Oyster Worker. The easy operation of the oyster farmers allows them to use the oyster chair to reduce the occupational injuries caused by long-term squatting and shelling before and after breeding, and reduce the chance of hand cuts. Oyster Worker uses recycled oyster shells as materials to achieve the benefits of local materials and recycling
