Two IKEA gold wall shelves, they are still selling on IKEA so you can see the details here: https://www.ikea.com/gb/en/p/svenshult-wall-shelf-gold-colour-50427533/
There are no fixings that come when you buy them so you will need to find your own but they are very easy to mount.
Pick up only from Clapham Common area, London SW4.
