Color: Yellow Description: A set of 10 four sided sanding block nail files designed to smooth and shape uneven nail surfaces before applying polish or nail treatments. Each block is made from very dense sponge with an extremely fine abrasive on all four sides for consistent, gentle filing on natural and artificial nails. Key benefits: Prepare nails quickly and evenly to improve polish adhesion and finish. Four distinct surfaces allow shaping, smoothing, buffing, and shining with a single tool. Dense sponge core holds shape during use for even pressure and predictable results. Compact size and lightweight design make these blocks easy to handle for salon professionals and home users. Features: Color: Yellow Quantity: 10 pieces per pack Size: approximately 9.5 x 2.5 x 2.5 cm Material: very dense sponge with extremely fine sanding on four sides Compatible with natural nails, acrylic nails, gel polish, and UV polish Suitable for professional salon and home manicure and pedicure use How it solves common problems: Eliminates ridges and uneven surfaces that cause polish to look patchy. Replaces multiple singleuse files by offering four functional surfaces in one compact block. Reduces the need to press hard or overfile thanks to even sanding and a firm sponge core. Typical use scenarios: Professional salon manicure: use the coarse side to shape acrylic extensions, the finer sides to smooth and refine, then the finest side to create a smooth base before applying gel polish. Home nail prep: quickly even out natural nail surfaces and remove light ridges before a home polish or treatment application. Pedicure touch ups: smooth toenails and refine edges before painting or applying treatments. What is included: 10 pieces of 4way sanding block nail files Practical notes: Use light, even strokes; avoid aggressive pressure to protect natural nails. Clean blocks by wiping with a dry brush or cloth; when abrasive surfaces wear down.
