Kal-Stamps is a service provided by the Kaldan Postal Service. One would be required to set up an account with Kal-Post, and once the account is setup, they will be charged a monthly fee in addition to needing to purchase postage. However, this saves the user time, and money from having to go to the post office, or order stamps in bulk. One could send domestic or international mail, and all mail sent with using Kal-Stamps will have automatic tracking available.
Kal-Stamps will only work in the nation of Kaldus. Just as you can’t use US postage to pay for mailing an envelope in Canada, Kaldan postage must originate in Kaldus. With this in mind, only Kaldan addresses will qualify for using this service. K-Stamps can still be used to print envelopes.
