In the case of correction tape rollers, the ink is contained on a tape that aids in applying the ink to the paper during use. The length of the tape determines the product's lifespan as well.

The tape width determines the width of the error correction roller that will cover the text to be corrected.

Once the error corrector has been used, if the document is photocopied, whether or not the photocopy will show any noticeable use of the error corrector.

The product is made partially or entirely using recycled materials.
