Hair:Goat & Synthetic fiberQuick and easy foundation makeup application to achieve a flawless finish. It has a unique shape; synthetic fibers are arranged with 2mm shorter goat hair as if it has a 'layer' on the top. This specification enables synthetic fibers to open up evenly to pick up then distribute moderate amount of pigments; and to have a bouncy texture which help your application easier. Please try to use surface of the brush (try not to touch shorter goat hair on your skin) and tap on as stippling to apply; then blend them out with a gentle circular motion. You will see your natural makeup while also helping your makeup lasting longer. This brush works perfectly with any type of foundation - liquid/cream and even powder.
