The Pen Friend Labeller is incredibly simple but truly ingenious! You can put labels on numerous products including food cans, letters and books. It's a really handy size - like a very chunky pen - and it comes with 127 small labels. All you have to do is stick the label to the item you want to name. Switch the pen on (it makes a single bleep), touch it to the label and after another bleep you talk into the 'pen'. Once items are labelled you just need to touch the pen to the label and it tells you what that item is. A brilliant aid for people who are visually impaired.
