This is a Kickstarter project. NOTEBLOX look like typical bound notebooks, but they have a difference: magnets are buried in the bindings. These magnets can be used for a variety of purposes, like simply holding the notebooks together in a neat block or holding a pen or stylus to the front cover. Magnets in the back cover can even hold your newer iPad inside the back, so your pen-and-paper notebook also acts as an iPad cover. An early-bird pledge of $15 gets you one notebook; the pledge will be $20 after the last few early bird slots are gone. There are similar early-bird specials for multiple notebooks.
Thanks to Anson for bringing this to our attention.
