This set of 48 Medium Files comes with a free Display! Dimensions: Display with files dimensions : 4.6" x 3.2" x 8.8" MATERIALS: Our glass nail files are made from the finest Czech crystal glass, manufactured without lead or added chemicals and formulated and tempered for durability. Unlike traditional emery boards, which can wear out or become dull over time, glass nail files are extremely hard and long-lasting, and can be easily washed and sanitized. I use enamel paint to design and create each file myself. They are then baked at low temperature to secure the image and prevent fading or chipping of the artwork. Each file comes in a white plastic protective sheath. USE: Our glass files can be used either wet or dry, and in both directions. The fine-grit surface allows for easy shaping without causing microscopic frays and gouges on either nails or cuticles. Resulting in stronger and healthier nails! CARE: Just rinse with water after use and pat dry - removing any debris. SHIPPING: Most orders are ready to ship so processing is only 2-3 business days. Shipping is with USPS and averages 2-5 additional days depending on your location. During the holidays it can run a few days longer.
