Tom Ford Beauty Deeper (01) is a slightly cool-toned, dark black with a matte finish. It is a permanent eyeliner that retails for $55.00.
Tom Ford Deeper (01) Eye Defining Pencil Pen ($55.00) is a double-ended liquid eyeliner with a calligraphy brush on one end and a squatter, thicker felt-tip on the other. It's a very deep black (and frustratingly, I still can't get my black liquid eyeliners to really photograph as black as they are--they always turn brown-ish), but I can assure it is an incredibly rich, deep dark black.
The intuitive Tom Ford Eye Defining Pencil Pen features a fine calligraphy tip on one end and a pro brush on the other for the ultimate in precision lining. The deep carbon black liquid liner delivers a spectrum of effects from sleek lines to dramatic wing tips or a full doe eye.
