Coffin nails is the description of a nail shape. Some describe it as a long nail like a stiletto but with a blunt end and angles at the sides in the shape of a coffin.
Some also call it a “ballerina”. However, ballerina-shaped nails have a little more rounded sidewalls, as opposed to the very straight sidewalls of the coffin shape.
