A smell proof bag is a type of bag designed to contain and conceal strong smells and odors. These bags are often used to store items that have a strong smell, such as herbs, spices, or cannabis. Smell proof bags are typically made with materials that prevent odors from escaping, such as activated carbon or Mylar. They also usually feature airtight seals or closures to ensure that no air or odors can escape. Smell proof bags come in a variety of sizes and styles to fit different needs, from small pouches to large duffels. They are popular among travelers, hikers, and anyone who wants to keep their belongings discreet and odor-free
