This zipper uses ultrasonic to melt the bottom teeth and form the bottom stop, effectively preventing the edges of metal or injection-molded bottom stops from causing skin scratches. This zipper enhances both safety and comfort to some extent.

SBS recommends using this zipper for products such as skirts, formal dresses, shoes, boots, backpacks, and handbags. The zipper tape, slider, and puller are available in a wide range of colors for customers to choose from, meeting diverse product needs.
