A quality zipper makes all the difference in the final product. It is important to assess its strength, whether it has an adequate finish to prevent breakage, and its size, so that it is in accordance with the standard used in the market. Check whether the zipper glides without jamming when opening and closing, and whether its teeth and components are uniform. SANCRIS zippers are manufactured following strict quality control and undergo several tests throughout the process, to ensure that the consumer receives an excellent product.
