I received the 4 piece set of this as a gift and LOVE it! First of all, Butter London's formula is so smooth and has amazing coverage. One coat of it gives full color and is good enough if you're short on time! Secondly, it has long wear. Thirdly, the colors are just so beautiful! The rose gold color in this collection is my favorite - it's super metallic and is a true rose gold. This is a great gift to any nail lover!
