The DelGuard ER has the same great spring loaded tip that protects your lead while you’re writing, with the addition of an automatic eraser! The eraser comes out on its own when you turn it upside down to use it, and tucks away when you go back to writing. It’s like a magic trick! The DelGuard ER is available in .5 mm tip size and your choice of barrel color. Each pencil comes with a set of eraser refills, and additional DelGuard Eraser Z Refills are available. We recommend DelGuard Lead with this pencil. Only load 2 leads at a time to help avoid jamming.
