This ultra slim eraser is a mere 4.5 mm thick, perfect for slipping into your pen case. It's handy for when you need to precisely erase a certain area without disturbing other parts of your work. You can also use it when filling in forms that are read by optical character recognition (OCR), such as "scantrons" or "bubble sheets." The small size allows you to erase individual bubbles without erasing the surrounding bubbles. The eraser gives a soft light feel as you erase.
When not in use, the eraser should be stored in its sleeve.
