Thin enough to fit in your pocket, the Worley FlatLight by Tater Tot Designs is a compact flashlight that you can take with you anywhere you go.
Almost the same size as a credit card, the FlatLight can be stowed away in your purse or even your wallet, and won't add lots of bulk. It uses fiber optic light that creates a personal space of dispersed light that allows your eyes to adjust quickly without causing any strain. This is especially convenient if you don't want to disturb the person next to you.
The Worley FlatLight is customizable so brands can put their logo on the back and give them out as part of their brand promotion.
