The Mr. Pen Compass and Protractor set is a high-utility, entry-level kit designed for K-12 education. It stands out by including 15+ items, such as a 6-inch swing-arm protractor, which is rarely found in standard budget bundles. The compass is built with a zinc-alloy and polymer hybrid chassis and features a lockable arm mechanism to help maintain consistent measurements during use.
The transparent rulers and protractors are made from high-impact polystyrene, ensuring that students can see their coordinate points clearly. All scales are printed with high-contrast UV-cured ink for long-lasting legibility. The set is housed in a carrying case that provides a dedicated spot for every tool, including lead refills and an eraser. For younger users, the sharp needle point of the compass provides great rotational stability, making it easier to learn geometric constructions.
If you prefer a kit with a metal storage tin for extra protection against bag damage, the Staedtler 10-piece math set is a rugged alternative.
