Setup, Compatibility & Care
Setup: No setup is required. Simply place the ruler directly over the text you wish to read on a book, document, or printed page.
Compatibility: These rulers are compatible with most standard printed materials, including books, magazines, reports, worksheets, and documents.
Care: To clean the rulers, gently wipe them with a soft, damp cloth. Avoid using abrasive cleaners or solvents, as these can damage the PET material. Store them flat or in a protective sleeve to prevent scratching or bending. Ensure they are dry before storing.
