This straw tamper-evident drink seal is the perfect seal for any delivery or take-out drinks. Use this with your restaurant to give customers peace of mind that their drink is tamper-free from the restaurant to their house. When the drink opens, the seal breaks, clearly showing has tampered with the drink. If you would like to see a similar seal in action, be sure to check out our Youtube video! As you can see in the video, these tamper seals are awesome because you don’t have to remove the label to use the straw hole. There are slits in the straw hole that allow you to put the straw right through the stickers. However, you will still be able to tell if your drink has been tampered with if they use the straw hole because it is clear after punching through to use it.
