The Yoropen Ergonomic Ballpoint pen allows children (and adults) to see exactly what they're doing, due to the design of the revolutionary grip and nib. Toby, aged four and three-quarters, enjoyed writing with the Yoropen, especially when practicing his letters.

 I noticed that he became more considered in the way he wrote which I put down to his ability to see the page more clearly as a left-hander. Although it's too early to say whether it offers any major benefits over a conventional pen, we found that he liked writing with it and certainly found the design cool.
