I bought the EcoTools 5 Piece Brush Set from here, for just £3.78, including P&P. Boots are selling it for £19.99, so that's a hefty saving. However, I'm not sure if they're authentic. You can never be too sure with eBay. They look and feel authentic, but there are people who go to great lengths to deceive their customers. It's hard to tell whether they're fake or not because even the real ones vary from brush to brush because of the natural materials they are made from. My little cosmetic bag is different from some photos I've seen, but some authentic sets also have the same bag, so I'm not sure. Regardless, I'm still going to use them. They're really soft and feel like good quality. I'll use the powder brush and baby kabuki the most. I don't apply concealer with a brush and I rarely wear eyeshadow, so the two smaller ones aren't of much use to me. I would never use fake make-up though - You don't know what it contains! An eyeshadow could be bulked up with some cheap powder. Overall, I like the set (and the price!).
