The Global Forever stamp can be used to mail a postcard or 1-ounce letter-size letter anywhere in the world by First Class Mail International delivery, according to the U.S. Postal Service. In 2014, a Global Forever stamp costs $1.15. Heavier letters and packages require more postage.
Other services, such as Priority Mail International or Priority Mail Express International, get mail to Holland more quickly but at much higher cost. The USPS has a postal rate calculator on its website to assist in choosing among the types of service. International mail also has limitations on what can be sent. Mail to Holland cannot include weapons, human remains, live plants or animals, radioactive materials or lottery tickets.
