For use with Standard 0.15oz Round or Oval Lip Balm Tubes, these shrink bands create a tamper evident seal when paired with .15 oz round standard lip balm tubes and will even work with our oval lip balm tubes. Our Clear shrink bands are 2 mil thick and, after applying using a heat gun form a tamper evident seal that can be opened by pulling the single vertical perforation. Use these clear shrink bands with Standard for a cost-effective, elevated look.
