Here is the collection, can you see why I am tempted?

Left to right the colours are (with Butter London's descriptions):
Blowing Raspberries: Rich, delicious berry lacquer. Perfect for in-between days when red is too much and pink is too little;
Muggins: Not your mother’s lilac. A opaque shade that’s pale, but packs a punch;
The Old Bill: Burnished copper with a beautiful antique patina. For sophisticated metal heads;
Artful Dodger: This true teal is a show-stopper. High fashion and so unique, it’s the perfect way to wear this trend without over kill;
Cheeky Chops: Why no, I do not have a banana in my pocket, but I am happy to see you.
I am particularly coveting Cheeky Chops (and I'm not normally a huge fan of yellow), and The Old Bill and Artful Dodger and ... well all of them actually.
What do you think, should I buy them? They're available here, and if you've tried them or other Butter London products I'd love to know what you think.
