VLUV Veel Seat Ball with Microfibre Faux Leather Cover

I would like to sell my VLUV Veel Seat Ball with Microfibre Faux Leather Cover. The color is something called "schlamm". I only used it indoors as a chair for work. Its on the big size (70-75 cm). Its in real good shape and I have been using for three years I reckon. Its made of two layers -- you deflate it, open up the zipper and the inner comes off, so its easier for transportation.
