Child-Guard Barrier Zipper Pouches are made with the latest technology and materials. They are puncture-resistant, tear-resistant, child-resistant, tamper proof, smell proof, opaque, and can be used over again. The bags are designed with a single zipper, containing a dual lock mechanism to ensure dried herbs, edibles, concentrates, and other products can be safely packaged and transported with minimal smell. The Child-Guard slide closure used on the bags has passed the Consumer Product Safety Commission's (CPSC) standards for poison prevention packaging (PPP) Code of Federal Regulations (C.F.R.) Title 16 Part 1700. The bags are also UV-resistant, freezer-safe, BPA-free, and made in the United States.
