Care Precautions

• Surface Protection: Avoid using the ruler as a prying tool or scraper, as this can nick the measuring edge and affect straight-line accuracy.

• Storage: Store flat or upright in a pencil bag to prevent the ruler from being bent under the weight of heavy textbooks.

Frequently Asked Questions

• Is it shatterproof? While the high-impact plastic is highly flexible and resistant to breaking, it is not classified as "shatterproof" like the Scholar range.
• Does it have inches on the other side? This specific Penflex model is a metric-only ruler, focused on the centimetre and millimetre scales used in the South African curriculum.

Quick Stationery Hack: The "Steady-Grip" Ruler

• If your ruler keeps sliding while you're trying to draw long lines, stick two small pieces of Bostik Prestik to the underside. This provides a non-slip grip on the paper, allowing you to draw perfect, steady lines without the ruler shifting midway through.
