High-Quality Materials: Our nail buffer blocks are made from high-quality sponge and EVA emery materials, making them durable, easy to use, and resistant to breaking or bending. Small in size, lightweight, easy to carry, gentle on the skin, and long-lasting. Double-Sided Nail Buffer Blocks: These blocks feature different grits (100/180 grit) to meet various needs. The 100-grit nail file is suitable for filing hard fingernails and toenails, removing nail glue, and polishing nail caps. The 180-grit side is more useful for trimming and shaping nail edges, suitable for natural or acrylic nails.
