This is the coolest keychain you've ever seen. And one of the neatest things in general. You know those keychain viewers they try to sell you at amusement parks? Well this is the same idea. When you put your eye up to the eyehole you will see a magnified image that will look 10 feet tall.
What you will see is a complete Tip Chart as shown above. No need for your glasses and no one will know what your looking at.
There is no way you could ever get all this on a regular keychain. It would be waaaaay too small.
