The ThumbTab RVBC series is a premium pharmaceutical packaging solution designed for patient ease and safety. The 13DR (13 Dram) size is one of the most versatile capacities, ideal for standard tablet and capsule prescriptions. These vials feature the "Thumb Tab" mechanism, which allows patients (especially those with arthritis or limited hand strength) to open the container with a simple press of the thumb, yet they remain secure when closed. The RVBC designation often refers to a "Reverse Benefit Cap" or similar dual-purpose closure system that can be converted between child-resistant and easy-open modes. These vials are typically translucent amber to protect light-sensitive medications from UV degradation
