Remember when you were a kid and there were those voice activated electric lock diaries? Did you want one and never got it? That’s depressing, I know. You’re an adult now and can get whatever you want though! Like the locking diary of your dreams. Check out the Lockbook, the fingerprint locked notebook.
You can use this to write whatever you want. It has refillable pages so when you run out paper, just add more. There are also card pockets for carrying around whatever you would like. Like photos or note cards. Whatever you want that can fit into a card pocket.
The whole thing is locked up with a fingerprint sensor which is, really cool actually. It charges via USB and comes in a few different colors. You can get one for $79 if you want to keep all your secrets to yourself.
