Round nails:

Choosing the option that states round nails mimic the cuticle line and might be slightly tapered on the sides accurately describes the characteristics of this nail shape. Round nails are designed to reflect the natural shape of the fingertip, blending smoothly with the cuticle line. This design not only enhances the overall aesthetic but also allows for a more natural look, making it a popular choice among clients who prefer a softer appearance. The slight tapering is subtle, contributing to the rounded shape without being overly dramatic.

The other options presented describe different nail shapes. For example, having straight side walls with sharp corners aligns more with a square or squoval shape, where the angles are more pronounced. Tapered nails, on the other hand, refer to a more elongated and narrow shape, while sharp points are characteristic of stiletto nails. Understanding these distinctions is crucial for a nail technician to provide the desired service accurately.
