1.) Slide in your device – Twist the clasps outward to open the DryCASE, and then simply slide in the device that you would like to protect.

2.) Lock the closure shut – Twist the clasps inward to close and lock the DryCASE. Position your device how you would like to use it inside the DryCASE. When you remove the air creating a vacuum it will secure the device in place

3.) Pump out all the air – Simply squeeze the pump until you have removed all the air and can't pump it any more. After you have removed all the air the DryCASE should be tightly sealed around the contents inside and the pump should be completely flat. You can now remove the hand pump and place the safety cap on.
