All our products have a lifetime guarantee from any defects that may occur. Since all of the products are made in Germany and Italy, it occurs very rarely. In the event you have any problems or questions about any product, please email us at email@example.com or call us at 718-645-2469. We also sharpen all our tweezers and scissors in house. This takes around 3-4 weeks. Unfortunately, there is a small charge but you can inquire when you are ready to sharpen your tools.
