Our synthetic shanks exceed FDA and US Food Regulatory and Safety compliance guidelines. The shanks will not impart any color, odor or flavor to the contents of the bottles, nor will they crumble, chip or break. Also, our patented injection molding process is designed to keep our shanks from separating from the T-Tops.
