Great Question!
A Pocklette™ is a bit larger than 4x6” when it's closed. In comparison, passports are about 3.5x5”.
Let's say you're packing for a trip and want to keep a few things safe while you're exploring a new town. You decide to conceal your passport, AAA card, credit card, and $60.
Check it out - it all fits inside the Pocklette™.
The real test will be if it's possible to conceal under your clothing. You may need to try out a few different shirts to make sure no one can tell you're wearing a Pocklette™.
