From the manufacturer:

Say goodbye to soggy notepads and forgotten thoughts with Aquanotes-a waterproof and shower-friendly notepad. There are a lot of times when having a notepad in the shower would come in handy. You could multitask by organizing your day, writing to-do or grocery lists, and record your brilliant and creative thoughts that often only appear in the shower. Before Aquanotes, I had to either try and remember my inspired ideas until I was out of the shower, or write on soggy paper. But with this waterproof and durable notepad, I can even write underwater!
