This is a great idea for folks like me who do their best thinking in the shower. Here's the product description from their website:
"The shower has long been held as the best place to spark ideas and creative inspiration. But it’s always been a challenge to remember shower ideas, and writing in water is a struggle. That is until now! AquaNotes® is a waterproof notepad that allows you to record your great ideas while you're in the shower. It's so durable you can even write underwater. They're recyclable, environmentally friendly, and the notepad is printed with soy-based ink."
