7PCS Ruler Set, Plastic Ruler 30CM 20CM, Transparent Rulers, Protractor, In and Metric,Suitable for School, Office.Can Also Undertake Surveying Work for Engineers and Architects.

• 1. Complete 6-Piece Measurement Set This practical set includes everything for precise work: 2 fully transparent rulers (20cm/30cm or 7.87in/11.81in), 1 solid protractor, 1 versatile 18cm (7.08in) ruler, 1 isosceles right triangle ruler, and 1 right triangle ruler. It's the all-in-one solution for geometry, drafting, and everyday measuring tasks.
• 2. Clear, Durable & Safe Material Crafted from high-quality, sturdy yet flexible transparent plastic, these rulers are built to last. The clarity allows for unobstructed viewing of your work underneath, enabling more accurate marking and measurement, while the smooth edges ensure safe handling for both adults and students.
• 3. Dual-Scale Precision (CM & Inches) Each clear ruler features two measurement scales on opposite edges—centimeters on one side and inches on the other. This allows you to measure item length directly in either unit system without the need for conversion, saving time and reducing errors in international or multi-standard projects.
• 4. High-Contrast & Finely Graded Scales The translucent body is paired with crisp, black printed scales for excellent readability. Scales are finely divided, with inches marked clearly down to 1/32. The variation in line length makes precise measurements easy to achieve for detailed technical work, crafting, or academic use.
• 5. Versatile Tool for Multiple Users This geometry ruler set is an essential tool for a wide range of applications. It perfectly serves students in math class, teachers preparing lessons, engineers and architects in design, artists in creation, and is equally handy for office tasks or DIY projects at home.

1. Set configuration It includes 2 transparent rulers (20/30CM), 1 solid protractor, and 3 triangular rulers with different functions (including 18CM rulers) to meet a variety of measurement needs. 2. High permeability material Made of high-quality plastic, it combines toughness and durability, and the transparent design ensures a clear and unobstructed view during measurements. 3. Dual standard scale The centimeter and in double-sided scale does not require unit conversion, and the measurement data is directly read to improve work efficiency. 4. Precise application The precision scale (accurate to 1/32 in) is suitable for learning, teaching, design and other scenarios, and is a practical tool for office and learning.
