Yes! On the 11.2oz and 25.4oz cartons, there are 3 plastic prongs connecting the cap to the container, which break the safety seal when opening the carton for the first time. These prongs can be seen on the bottom edge of the cap and will be intact before opening, and broken after opening. You will not be able to see the inner seal once the product has been opened. Additionally, we include connections on the cap to show that the product has not yet been opened.
On the 16oz and 32oz cartons, there is a two-step screwcap. To open the carton, you will unscrew the lid and lift the pull-ring.
