I recently tried the glass nail files from https://germanikure.com/collections/glass-nail-files german glass nail file and I’m genuinely impressed. Made from 3mm thick Bohemian glass, these files feel incredibly smooth and durable compared to regular emery boards. They seal nail edges while filing, reducing brittleness and promoting healthier growth. I love that they can be used wet or dry, sterilized easily, and last for decades—definitely a sustainable choice. Plus, the motivational phrases add a surprisingly calming touch to a simple nail care routine. If you’re serious about nail health, this is a must-try.
