The OPI Start To Finish Base & Top Coat is a breakthrough, three-in-one nail treatment that combines a base coat, top coat and natural nail strengthener in one high-performance product. As a base coat, it can be applied before nail lacquer to prevent staining and to strengthen the natural nail. Also provides a smooth base for the application of OPI Nail Lacquer.

As a topcoat, the OPI Start To Finish dries quickly to give a high gloss shine. As a nail strengthener, it helps to bond nail protein fibres, a process which hardens nails and prevents moisture loss.

The result - stronger, more flexible nails.
