Students, teachers, and anyone who needs reliable math tools, this Westcott 2-piece set is exactly what you need for geometry and drafting work! The compass can draw circles up to 13 inches in diameter and includes a handy 6-inch ruler on the side - such a smart design that means one less tool to keep track of. The protractor is shatter-resistant and also features a 6-inch ruler, making it durable enough for classroom use. I've been using this set for tutoring geometry students, and the quality is noticeably better than the cheap plastic sets - the compass holds its adjustment securely, and the protractor has clear, easy-to-read markings. The colorful accents make them more enjoyable to use, and they come in assorted colors (though you can't choose specific colors when ordering). Whether for school, office work, or home projects, these tools deliver professional performance at an affordable price. They've become my recommended set for students because they're reliable, easy to use, and built to last through the school year. The compass has an easy-grip top that makes adjusting much simpler than cheaper models. Definitely worth having if you need quality math tools that won't let you down during important assignments or tests!
