The Drop-n-Tell indciator will show whether or not your package was dropped. Once your packet has exceeded its G-Range, 2 black arrows will appear on the device. The Drop-n-Tell represents a preventive care product by alerting shippers and handlers that this package is fragile and has been monitored by visibly sticking the Drop-n-Tell label as a warning. The shipping indicator can be glued to your package by removing the protective paper on the back to secure the future of your package!
