        "description": "\u003cp\u003eBall bearings in the pivot joint eliminate the wobble that plagues basic student compasses. This Westcott compass maintains its radius setting through repeated circles, so you're not constantly readjusting between arcs. The mechanism holds firm enough for technical work yet adjusts smoothly when you need to change diameter.\u003c\/p\u003e\n\u003cp\u003eDual-scale arms show both inches and centimeters, useful for projects requiring metric conversions or working from European technical drawings. Maximum 13-inch diameter capacity handles everything from small geometry exercises to large format design layouts. The included pencil slots into a secure holder that keeps the point positioned correctly, no tape or makeshift solutions needed.\u003c\/p\u003e\n\u003cp\u003eStraightforward construction means less time figuring out how the tool works and more time actually drawing. Math students working through geometry proofs appreciate the reliability; architects and designers doing preliminary sketches value the quick setup. The ball bearing mechanism costs slightly more than friction-joint compasses but delivers noticeably better performance when accuracy matters.\u003c\/p\u003e",
