What type of nail art can be created with decals?

Decals are versatile tools in nail art that allow for a wide range of designs to be easily applied to the nail. The correct answer highlights that various designs can be created with decals, which makes them accessible to both beginners and experienced nail artists. This versatility includes everything from intricate patterns to simple images, catering to different preferences and styles.

Decals are pre-made designs that can be applied effortlessly, usually requiring only the application of a top coat to secure them onto the nail. This ease of use emphasizes their appeal, as they can be used by anyone, regardless of skill level, to enhance their nail appearance without the need for drawing or painting techniques.

The other options suggest limitations that are not reflective of the true capabilities of decals. Simple patterns, complex 3D designs, and professional skills are not necessary when using decals, which can accommodate a broad spectrum of creativity and design complexity.
