Apparently no one has yet developed a "note taking" app which would make this obsolete. Oh wait, yes they have. Oh well.
If you’re the type of person that constantly sticks little Post-Its on the back of your iPhone, this is the notepad you’ve been looking for (but never knew you were). The Paperback Notes are simply sticky notes sized perfectly to fit on the back of your iPhone 5. There’s a cutout for the camera (but not the flash). Stick on a single or a small stack and have a handy notepad with you at all times. You say, “there’s an app for that”? Well, why not “think different”? 80 sheets per pad.
Here's the LINK to 80 sheets of Post-It iPhone fun.
