First, one must understand the history of stamps. Stamps were originally used in the late 1700s to issue paper currency and as a way for governments to collect taxes. Companies such as the East India Company were the first to issue stamps for commercial purposes. In 1855, the British postal system began with a low value stamp that was honored from all over the world. The first postage stamps consisted of ink on paper and the first adhesive stamps were created in 1867. In 1874, stamps were made of rubber. In 1879, they were made out of celluloid, and they have been produced since that time in various materials such as gelatin and then polyester film. The British have been using a central post office, which means that mail is delivered directly to the local post office or other locations that are set up by the government. This is significant because each piece of mail is stamped with a postmark to identify where it came from and where it was delivered. Kwellam is a company based out of Chicago, Illinois that produces unique stamps and ink pads that make writing easy for everyone. Kwellam's ink pads come with a two-toned ink that allows you to write with black ink on one side and red ink on the other side. They are also available with different colors of inks. Kwellam's stamps are also versatile because they can be applied to paper or other surfaces such as metal, wood, or plastic.
