Ob Cosmetics Two Stand Holders One purchased at a beauty salon, the other online. The design of the base is different, possibly due to the different purchase times. I'm not sure why... please check the photos. There is no rust, but they are used. I no longer need them, so I'm offering them to someone who does. The eco-size shampoo and treatment (1,000ml/g) can be used with the pump and stand holder set.
