Which nail shape is created by filing from the corner to the center?

The nail shape that is created by filing from the corner to the center is the oval shape. This technique involves gently rounding the corners of the nail while keeping the center slightly fuller, which results in a graceful and elongated appearance. The oval shape is particularly popular because it can complement various hand shapes and looks more natural on the fingers.

Filing from the corners towards the center helps to achieve this smooth contour, rather than a sharp or straight edge, which is characteristic of other shapes like square or square-tipped. Hence, the method of filing described in the question points directly to the oval shape being created. The other options, such as square, require a different filing technique that creates straight edges, while almond shapes involve a more tapered approach that does not strictly adhere to filing from the corner to the center.
