It includes three types of compasses (study, graphic, bow), a divider, extra leads, two protractors (standard and swing-arm), a 6-inch ruler, two triangle squares (45°, 30°/60°), two mechanical pencils (0.5 and 0.7 mm), pencils, erasers, lead refills, and a case. The set is designed to produce smooth circles up to 6 inches in diameter and offers adjustable components for precise arcs and curves, making it a strong option for students and aspiring designers alike.
Unjoo Math Geometry Kit Sets 10 Piece
The Unjoo geometry kit emphasizes practicality and durability. It includes two metal study compasses, two triangles (45° and 30°/60°), a 6″ ruler, a 4″ protractor, a pencil for the compass, a pencil sharpener, an eraser, lead refills, and a universal compass holder compatible with standard pencils or pens. The metal components resist bending, and the ergonomic design supports comfortable, extended use. This kit suits classrooms and personal projects requiring dependable performance and clear measurement scales.
Drawing Compass And 6 Inch Protractor (EBOOT)
The EBOOT drawing compass kit combines a reliable compass with a 6-inch protractor for compact geometry work.

The protractor offers both inch and centimeter scales, with a 0 to 180-degree range, enabling accurate angle measurements. This option is particularly convenient for students who prioritize organization and straightforward setup in a single kit.
Buying Guide: Key Purchase Considerations
- Purpose and scope: For classroom use, look for a multi-piece kit with a variety of accessories (compass types, protractors, rulers, and spare leads). For professional drafting, prioritize durability, precision, and larger circle diameters.
- Material and build quality: Metal compasses (nickel-plated or stainless) tend to be more durable and stable than plastic options. Ergonomic grips improve control during extended sessions.
- Range and precision: Consider the maximum circle diameter you will draw and the availability of adjustable screws or extension beams for larger circles or arcs.
- Portability and storage: A sturdy carrying case or pouch helps keep tools organized and protected between uses. This is especially useful for students and field workers.
- Maintenance: Look for sets that include extra leads, replacement parts, and sharpeners to minimize downtime due to wear or loss of parts.
- Complementary tools: Protractors with swing arms expand capabilities for arcs and larger geometry projects, while combined rulers and triangles expand structural drawing options.
- Cost versus value: A higher-priced, durable set can offer long-term savings by reducing replacement frequency and improving precision during critical work.
When selecting a compass tool for math, evaluate how the components align with your typical tasks—circle drawing, angle measurement, or drafting—and choose a kit that balances breadth of tools with reliable performance and portability.
