The Urban Decay Naked Liquid Foundation comes in a 30ml bottle, and this listing is for shade 12.5. It sits within Urban Decay's cosmetics collection.

As with most liquid foundations, it is worth starting with a small amount and building up where you want more coverage, blending with a brush, sponge or clean fingertips. Testing a shade along the jawline in natural light is the most reliable way to check a match before applying all over.
