What is the second class large letter rate?

The second class large letter rate refers to a specific postal rate for mailing large letters or flat items, typically used for sending items like magazines, catalogs, and brochures. In many postal systems, this rate is generally lower than first-class rates but may vary based on weight and dimensions. It's important to check with the local postal service for the most current rates and regulations, as they can change and may differ by country.
