Rear boot hatchbag cover in black. Used for about 6 months in my Range Rover.
Does have some marks to it, would probably clean up well though.

Its the model where the rear seats cant be folded, but it does have the drop down tailgate cover.
The cover is quick to remove should you ever need to.

Paid £192.50 for it

I will take £80.00 with free delivery to mainland UK.

You will need a new fixing kit which is available from hatchbag for £9.75

How does it attach to the sides please?

I have had similar ones before that use Velcro and tape and they just fall off.

They attach using velcro and I too have had similar experience as you but then I did it properly and used a product called tar remover to wipe down the plastic before I stuck the velcro strips down and it stuck very well.
The cover also ties to a couple of points in the car.

I brought the hatch bag based on recommendation on this forum. Just ordered another one for my new car.

Do you have any photos of it in place? It also says model 2018 onwards, not sure if its any good for mine.
