When shopping for erasers, there are a few things to keep in mind.
First, consider what the eraser will be used for. If it needs to erase pencil marks, then a vinyl eraser is a good choice. If it will be used on ink marks, then a plastic eraser should be chosen.
Next, think about the size of eraser you need. Are you looking for an eraser for a single pencil mark or for larger areas? Be sure to select the eraser with the appropriate size for the task.
Finally, consider ease of use when selecting an eraser. Some erasers are rubbery and hard to use, while others are easier to grab and rub away mistakes. Choose the eraser that best meets your needs.
