The child-resistant cap is one of the countless regulations for placing different types of poppers on the market in accordance with the regulations. We adhere to these strict dispensing regulations for poppers at all times. However, the childproof cap is annoying to use, especially when things get wild and you want to open the poppers bottle quickly and easily. These high-quality comfort lids without childproof closures are absolutely leak-proof and are also suitable for permanent storage of the poppers after the session. These comfort screw caps thread size small – 5 pieces fit all bottles from the manufacturers Lockerroom, Oxymoron, Shelbora and Royal Hexagon. The lids do not fit the 25ml Retro-Line bottles from Lockerroom. Note: If children live in your household and you are constantly replacing the poppers bottle lid for your convenience, then please think of your children: Please keep the poppers bottles out of reach of children!
