Nail Health


While Bona Fide Beauty glass nail files are suited to most nail types, everyone’s nails are different. Some people have thick, strong nails while others may have thin, sensitive nails. 

If you find them too rough on your nails, try dipping the abrasive surface of the file in water in-between filing to help soften or dull the filing experience. Alternatively, soak your nails for 5-10 minutes prior to filing, this will help soften the nails.

Remember, take it slow. File and shape nails gently in regular short sessions over a few days. With regular, long-term use your nails will strengthen and become less sensitive to the filing experience.

If you find they are too fine grit or gentle for your nails, we recommend using them alongside other nail care tools, such as nail clippers. Use your clippers to remove the bulk of the nail. Follow-up with your Bona Fide Beauty glass nail file to expertly shape and smooth the nail's edge. Be patient. Give yourself time to adjust to this unique nail care tool.
