What must the dimensions be for first class package international service rolls?

The dimensions for First Class Package International Service rolls are specified as being between 4 and 36 inches. This means that the minimum length of a roll must be at least 4 inches, while the maximum length should not exceed 36 inches. This range is important because it ensures that packages are appropriately sized for international shipping and can be efficiently processed and delivered by postal services.

In addition to meeting these dimension requirements, packages must also adhere to weight limits and other criteria set forth by the postal services to qualify for First Class Package International Service. This holds true for different types of packages, including rolls, which are commonly used for shipping documents and similar items.
