This multi-tasking brush is designed to fit oh so snuggly in your eye crease. Its bristles are dense enough pick up and deposit product, but loose enough to blend color as they are applied. It also makes the perfect nose contour brush (hence the name). Like all of our brushes, it is made with the best quality synthetic bristles designed to work well with both cream and powder cosmetics and making them hypoallergenic and safe for sensitive skin!
