3 Stair gates (Hipsburn NE66)

There are 2 of the Mothercare stair gates with 1 small extension piece. There is one Cuggi stair gate with 2 extension pieces. They have only been used a couple of times at our house for the grandchild but they were gifted to us second hand so there are no instructions. In good condition and as far as I know all the bits are there.
