Senkary Nail Buffer Blocks 12-Pack 4-Sided Medium Grit (150) White — Portable Nail Files for Natural & Acrylic Nails

Senkary 12 Pack Nail Buffer Blocks are compact, four-sided medium-grit sanding blocks designed to smooth, shape and prepare both natural and acrylic nails for polish or treatments.

These white, 4-way buffer blocks come in a convenient 12-pack and feature a consistent 150-grit surface on every side for uniform filing and buffing. Each block measures 9.5 x 2.5 x 2.5 cm and weighs about 6 g, making them portable for salon use or at-home manicures. The dense sponge core provides support behind the sanding surface so you get even pressure and fewer snags while shaping, smoothing ridges, or prepping nail beds before polishing.

How do these blocks help me get salon-smooth nails at home?

The four-sided design lets you perform multiple steps—shaping, evening ridges, smoothing edges, and final buffing—using one tool. The medium 150 grit balances material removal and gentle finishing, suitable for both natural and acrylic nail surfaces. Using them before polish helps the product adhere better and look smoother.

• Four working faces for shaping, smoothing, and light buffing
• 150 grit removes snags without aggressive thinning
• Dense sponge core gives controlled pressure and fewer chips
• Washable surface for multiple uses in a pack of 12

How should I use a 4-sided buffer on natural vs acrylic nails?

On natural nails, use light, gentle strokes and focus on evening ridges and creating a smooth surface rather than heavy material removal. For acrylics, the medium grit is effective for shaping edges and taking down small imperfections; avoid over-sanding to prevent damage. Always finish with a clean wipe and apply cuticle oil or polish base as needed.

• Natural nails: short, gentle passes to smooth and shine
• Acrylics: moderate strokes to shape and refine edges
• Finish: clean residue then apply base coat or nail treatment
• Replace when grit becomes worn or uneven

Are these blocks suitable for professional salon use and are they reusable?

The 12-pack gives salons economical options for single-client use or multiple sessions; they’re durable enough for repeated use when cleaned properly. Because each side has the same medium grit, you can rotate faces during a service for consistent performance. Replace blocks once the grit smooths out or becomes clogged to maintain effectiveness and hygiene.

• Bulk 12-pack supports salon throughput or home stock
• Washable to extend usable life between replacements
• Rotate faces to prolong even wear
• Lightweight and pocket-sized for travel kits
