Good fit and quality - careless packaging
Color: X40 Ultra/ L40 Ultra & P10 Pro /P50 Pro
OK - I'm happy with most of the kit. The dead corner brushes are crammed into small bag and bent out of shape. It looks like 2 of the 6 in the kit I received might be usable. Since I can get 3 of these for the cost of the OEM kit, I suppose I'm still ahead of the game, but it would be nice if a little more care was taken in the packaging.
