Key features:

• ColorSafe: Likely indicates the cap is designed to protect the contents from sunlight exposure, potentially preventing color fading or degradation.
• Reverse Cap: This suggests the cap opens by being pushed or twisted in the opposite direction of a standard screw cap. This design can be helpful for child resistance or ease of use in specific situations.
• 13 Dram: This refers to the volume capacity of the container the cap is designed for. 1 Dram is equal to 1/8 of a fluid ounce, so 13 Drams would be 13/8 = 1.625 fluid ounces.

Possible uses:

• Closures for various containers holding light-sensitive products, such as:
  • Pharmaceuticals
  • Cosmetics
  • Food coloring
  • Art supplies
