This item is no longer available for sale on
The Sun-Star Knock Free Sharp pencil combines the best of a conventional wooden pencil and a mechanical pencil! Winner of the 2008 Kids Design Award in Japan, this pencil is designed so that lead automatically extends while you are using it. Now, you can write continually without the need to stop and click for more lead! Incredibly convenient, this is one feature you'll love about it. Each pencil also features an eraser on top.

This set includes one pencil with lead tube already installed, and one extra tube. The set includes approximately 6 lead refills. See the instructions photo and caption to find out how to refill the pencil.

I just like the concept of a pencil that writes when you touch it to the paper. One mild problem I've had with these is that the lead really can't feed *back* into the pencil. I've had it in a purse and the tip accidentally touches the bottom so it feeds a lot of lead, too much to write with, and I've had to carefully grasp the lead, feed it all the way out and put it back into the barrel. That works, but it's a pain.

Best pencil ever!! I love the fact that it does not require you to push a button to extend the lead. This prevents over extending and breaking the lead. The eraser works beautifully. I will be ordering more!!
