Foursided nail buffer and sanding sponge block designed for nails and small craft surfaces. Compact white square shape makes it easy to carry and use at home or in a salon. Key benefits Multi function in one tool: four colored sides provide different abrasive levels for filing, shaping, smoothing, and shining. Saves time: move through the surfaces in sequence to reduce steps and achieve a smooth finish quickly. Versatile: suitable for natural nails, acrylic and gel nails, plus small woodworking and artwork polishing tasks where fine sanding or smoothing is needed. Portable and easy to store: compact square design fits into a manicure kit, desk drawer, or craft box. Features and attributes Construction: sanding sponge block design offers a firm but cushioned surface for controlled pressure and consistent results. Four color sides: each side has a distinct function to progress from coarse to fine polishing and final shine. Color and form factor: white square block, convenient handheld size for precision work. Performance: smooths ridges, evens surfaces, and produces a polished appearance when used in proper sequence. How to use Start with the coarsest side to remove spots or shape edges. Move to the medium side to refine the surface. Use the fine side to smooth and blend. Finish with the shining side to bring out a glossy appearance. Practical use scenarios Athome manicure: prepare and finish natural nails or enhancements with a single tool for shaping, buffing, and adding shine. Salon touch ups: quick smoothing between polish changes and for final finishing on nail enhancements.
