The Celestron 12mm Omni Plossl Telescope Eyepiece is a classic example of a 4-lens symmetrical Plossl design.

Each eyepiece is fully multi-coated for great light transmission. Fold-down rubber eyecups and rubberized grips come standard as well, and each eyepiece has blackened edges to decrease internal reflections. All in all, it's a great design and a great eyepiece for a small investment!
