The Memoring is a wearable post-it note ring. Great for jotting down notes on the fly or just for fun. The only thing is that to remove a note it looks like you’re going to have to either rip it on the bottom or take the whole ring off, because the top of the pad is on the inside of your finger facing your palm. Neat post-it idea though.
