The design of the Artis Elite Collection Circle 1R is produced using a proprietary premium metal alloy that has a luxurious density, increased durability, and feels even smoother to the touch. The Circle 1R has the same handle as the Circle 1 but the fibre bundle tips form a rounded dome. This rounded [the R in the name] edge allows for a soft, natural-looking edge to the application, which is preferred when spot concealing or blending eyeshadow all-over the lid or in the crease.
