We’re guessing that schools of fish would love to have the Waterproof notebook whenever they attend classes, especially with goldfish taking notes to stop eating when they’re full instead of bursting their intestines from within. We jest – this waterproof notebook can be used even in wet conditions, letting you write your innermost thoughts while taking a shower (or perhaps when you are scuba diving). Perfect to jot down great world-changing ideas when you’re in the bathtub and an eureka moment strikes. There are 80 pages in total, and it comes with an elasticated strap to keep it closed while holding a pen down in place. £8.99 is all it takes to bring this puppy home.
