Design a captivating set of nails inspired by the fresh and playful ethos of "btartbox nails." Begin with a crisp white base, setting the stage for vibrant geometric patterns that channel creativity and express individuality. Incorporate pastel and neon colors to contrast delicately against the white, creating an eye-catching pop art effect. Add a touch of holographic foil tips that capture light and add a magical shimmer, bringing an avant-garde flair to the design. Finish with a glossy top coat for that polished, high-fashion look.
