Here's a twist on one of the traditional office supplies...a business size envelope that has a badge window to make your registration line flow smoother and with less disgruntled travelers. These custom envelopes feature your logo or message in a prominent spot, with their badge front and center. You can even seal it if the contents are to be more secure (such as with tickets and card keys). Small promotional products, such as a pen or luggage tug, can even be inserted in the envelope for distribution.
