Safety Gate, Mama & Papas Deluxe safety gate - Never been used, still in sealed box ?

Mamas & Papas safety gate - deluxe - white. This safety gate is still in the box, and has never even been opened. When we had our first son we bought three safety gates as we live in a three story house, bout only ever got round to using two of them, this one has been stored safely in the garage and is about three years old. The minimum and maximum opening that the barrier is suitable for is 72cm to 84.6cm. We have standard stairs so it should fit any house.
