Nail file (banana strip) Sunone NF30 100/100

Sunone NF30 100/100 is a banana-strip manual nail file with a curved profile designed for professional and home manicure. The double-sided 100/100 grit provides a medium-coarse abrasive surface suitable for shaping, shortening and evening acrylics, hard gels and natural nails. Its compact, slightly concave shape improves contact with the nail edge and contours, making it easier to refine free edges and prepare the nail plate before polishing or applying extensions.

Advantages

The curved banana design gives improved control and better access to sidewalls and cuticle areas compared with straight files. Identical 100/100 grit on both sides ensures consistent performance during use and simplifies tool selection. The medium-coarse abrasive efficiently removes length and evens surfaces without excessive pressure, and the compact size is convenient for detailed finishing work and portable manicure kits.

Suitable for

• Shaping and shortening acrylic and hard gel nails
• Refining natural nail edges and contouring
• Preparing the nail surface before base coat or extensions
• Detail finishing in both professional salon and home manicure settings

Key specifications

• File type: banana (curved) strip
• Abrasive grit: 100/100 (medium-coarse on both sides)
• Double-sided abrasive surface for consistent performance
• Compact, ergonomic shape for improved control and access to nail contours

How to use

Use the Sunone NF30 100/100 by holding the curved file at a slight angle to the free edge of the nail and move in one direction with controlled, even strokes. For acrylics and hard gels, begin with gentle passes to remove bulk and then refine the shape with lighter strokes to avoid overheating or chipping. For natural nails, use minimal pressure and shorter strokes when evening edges to prevent splitting. Replace the file when the abrasive surface shows visible wear or reduced effectiveness.

Usage recommendations

For professional results, pair this medium-coarse 100/100 file with a finer grit buffer when smoothing the nail surface prior to polishing or applying top coats. Sanitize or dispose of the file according to salon hygiene protocols; single-client or disposable use is recommended for infection control.
