Mechanical Pencils Eraser Sizes & Info

We thought it might be helpful to keep track of which size eraser fits in which mechanical pencils. This is a very simple list. There could be oddities and exceptions. We've also listed known diameters of erasers we've measured and other little tidbits of eraser information. Whatever we come up with that might be helpful, we'll keep adding to the list. If you have a positive identification of pencil and eraser size, please drop us an email and we'll include it on this list. We hope this info is helpful to you!

Remember to save any metal sleeves that may hold or surround old erasers, you'll probably need them!
