The desk comes with a white board which is self- adhesive and stuck to the back of the desk. Within  24 hours the board had fallen off and peeled off some of the slat with it. 
We will now have to find an alternative way to fix it so the damage can’t be seen. 

Not a massive problem but slightly annoying with a brand new piece of furniture. In hindsight we wish we hadn’t attached the white board at all as it actually looked better without it.
