Youpai acrylic drawing ruler set with four-piece transparent square protractor for geometry and drafting, available in cool black 2505, blue 1919, simple 1389, simple 1390, drawing 1517, or eye protection 1525 configurations
Youpai transparent acrylic drawing ruler set with square protractor for geometry and drafting

This Youpai drawing ruler collection consolidates several essential measurement tools into one convenient set. Designed primarily for geometry, technical drawing, and drafting applications, the set's inclusion of a square protractor alongside straight-edged rulers provides a practical toolkit for students, designers, architects, and craft enthusiasts. The transparent acrylic construction is a key feature, allowing users to clearly see their paper or surface underneath for precise alignment and tracing. The product is offered in multiple distinct model configurations, each identified by a specific code and piece count, enabling selection based on individual project needs or preference for a particular set composition.
Features and Construction

The Youpai ruler set is defined by its material composition and the variety of available configurations, offering choice based on the specific tools required.
Material and Build
The rulers are fabricated from transparent acrylic. This material choice provides a hard, flat surface suitable for drawing against, while its clarity ensures that guidelines, underlying sketches, or graph paper markings remain fully visible during use. Acrylic is also resistant to warping and offers a smooth edge for ink or pencil guidance.
Size and Practical Fit
The source text specifies the product through its model variants rather than physical dimensions. The key practical differentiators are the model code and the number of pieces in each set. Customers can choose between the cool black 2505 (4 pieces), blue 1919 (4 pieces), simple 1389 (4 pieces), simple 1390 (4 pieces), drawing 1517 (3 pieces), or eye protection 1525 (4 pieces) configurations. The piece count directly affects the variety of tools available in a single purchase.
Uses and Placement

The set's design caters to both educational and professional environments where accurate measurement and angular work are required.
Event or Professional Use
In professional or academic settings like architecture studios, engineering design offices, or technical drawing classes, this toolset supports the creation of precise plans, diagrams, and geometric constructions. The square protractor is particularly useful for measuring and constructing specific angles, a common requirement in these fields.
Everyday Home Use
For home crafting, model building, school homework, or personal art projects, the set offers a reliable and organised collection of rulers. Having multiple tools in one set reduces clutter and ensures the right tool is available for tasks ranging from simple straight lines to complex angular designs in DIY projects or hobbyist artwork.
Benefits and Buying Value

The value of this product lies in its consolidated toolset, material clarity, and the option to select a configuration that matches the user's needs.
Reuse and Low Maintenance
Acrylic is a durable material that, with careful handling, can provide long-term service. The rulers require minimal maintenance; keeping them clean and stored flat will preserve their accuracy and transparency. As a multi-piece set, it replaces the need to purchase individual rulers separately, representing a consolidated investment in drawing tools.
Why Choose This Product
This Youpai set is distinguished by its transparent acrylic build and the explicit inclusion of a square protractor within a multi-ruler package. The availability of six specific model codes allows for a targeted purchase—whether one needs a three-piece drawing set (1517) or a four-piece set with features like 'eye protection' (1525) or a 'cool black' finish (2505). It serves users who require both straight and angular measurement capabilities in a single, coherent toolkit.
