Murrays 3 Stage Nail Buffer.
Pink side - polish across your nails for 15 seconds to even the surface and smooth any ridges.
White side - as before polish across your nails for 15 seconds. This will give a fine silky surface and sheen.
Grey side - polish your nails to a glossy shine.
Use the pink and white sides once a month - not more. Use the grey side as frequently as you like to keep your nails naturally polished.
