I have a tendency to buy loads of eye-shadow palettes and end up using only 1 or 2 shades, in the end 6 out of 8 colours are still full and I have to buy a new 1 just for one particular colour. With the Must have palette from Essence I can purchase only the shades I use a lot and refill them as they’re finished. I even bought 2 of the same colour. It’s a space saver too cause I only have to carry 1 container with all my favourites in my handbag.
