Hourglass Explorer GIRL Lip Stylo ($32.00 for 0.09 oz.) is a medium coral with warm, orange undertones and a cream finish. It had mostly opaque pigmentation that covered the lips fairly evenly, but this was one of the few shades that had room for improvement with respect to application. I think the slight streakiness was due to the consistency being more emollient and a touch thicker, so it slid around more on the lips, even though it certainly felt comfortable on the lips--rather balm-like. The color wore well for four hours on me and was moisturizing.
