This is a Medela Symphony double pump set. The main unit was rented and used. It was disinfected with Milton every time, so it appears to be in clean condition, at least to the untrained eye. The white valves of the pump are deteriorated, but there are replacement valves, so you can use them with peace of mind (*^^*) - Parts: Set of breast pump parts - Color: Clear/Yellow - Purpose: Breastfeeding
