These 3" Child-Resistant PET Vape Cartridge tubes are an optimal storage, travel, or marketing, solution for any vape cartridge up to 68mm in length and 16mm in diameter. This specific container stands above the rest due to its having no shoulder, leaving any contents easy to remove. This also allows for a flush interior fit along the full length of the tube. Push and turn child-resistant lid is NOT included. Ideal for oil cartridges. Extremely durable.
