Beautiful USA manufactured product that complies with new USP regulations pertaining to ferrules used in primary vial packaging.
For use on serum vials with 20mm rim to rim outer top diameter and 13mm hole opening (20mm crimp finish vial). These are referred to as "superior" in construction compared to regular flip caps because the aluminum seal is constructed with the hole already punched through the aluminum. This manufacturing characteristic reduces the risk that the aluminum tears inconsistently when the cap is removed. The aluminum stays "velvet-smooth" after removal of the plastic lid from the aluminum seal underneath. Several colors are available.
