Platinum paper nail art is a type of nail design that involves using a special type of paper with a metallic platinum finish. This technique is popular for creating a luxurious and sophisticated look on nails. To achieve this, the nails are typically painted in a base color, and then the platinum paper is applied over the top. The paper can be cut to fit the shape of the nails and is adhered using nail glue. Once dried, it can be topped with a clear coat to protect the design.
