Reversible Cap Vials Opaque Green received its name from the multi-function cap. It offers a Push-down and turns option to open and close the container. You can flip the cap over and use it as a screw-top container. Reversible Cap Vials Opaque Green is the perfect solution for any firm looking to stay compliant with child resistance safety laws in their states. Our Reversible Cap Bottles feature a two-sided cap which allows users to screw it on from both sides, just simply push down and turn to open the vial and release its contents. Their odor proof design keeps unwanted odors from lingering while keeping the contents fresh and preserved on the inside. Our Reversible Vials are the perfect choice for packaging anything from a flower to edibles. Our vials not only meet state standards but exceed the expectations of the ASTM and CSPC.
