The OHTO Horizon Auto-Sharp mechanical pencil has been cleverly designed to ensure the lead mechanism does not accidentally extend in your shirt pocket or pencil case.

The lead mechanism extends out of the barrel with one push of the top button, and a second push will extend the feed of the lead. The lead is then easily retracted by pressing the button on the side of the pencil. This mechanical pencil has a sturdy aluminium barrel with a hexagonal shape for easy grip, and uses a standard 0.5mm lead.
