Real Techniques Core Collection Kit contains four must-have beauty makeup brushes that will help to create flawless skin - the base of your beauty look. The kit contains a detailer brush which can be used to apply concealer, a pointed foundation brush which helps to build up liquid foundation coverage, a buffing brush which can be used to set your foundation with a translucent powder or just to buff the edges of your foundation to avoid any tell tale signs around the hairline and finally a contour brush which helps to create definition with bronzer or blush on the cheeks. The brushes in the Real Techniques range are all colour coded and each colour corresponds to a key step of makeup application. Gold focuses on the base - your foundation application. The brushes also come in a 2-in-1 carry case.
