We do not use heavy duty (toxic) glues to seal our products. Because we use a light weight sealer, the natural oils in our product can loosen the seal. It’s likely that this is what you experienced. In addition, the seal itself is designed to be lifted with the lid (when you twist open the top it automatically lifts the seal for ease of use). You will notice this type of (newer) packaging is used by major food brands, whereby the seal is broken by unscrewing the cap. You will know for certain that your product has arrived unopened by it being sealed inside of a plastic poly bag. Essentially, it is a double-seal by way of the seal inside the lid, along with the sealed plastic poly bag. As always, if you have questions or need assistance, please don’t hesitate to so we Contact Us can make sure you are completely satisfied with your order.
