2 Pcs New Upgraded Multifunctional Geometric Ruler Drawing Template Measuring Plastic Draft Rulers Graphic Design Tools for Architecture Designing, Students and School Office Supplies

Works as expected. I bought it for my daughter for drawing. She has struggled with circles and love to use this for making perfect circles.

Ordered a replacement when the first one broke (sacrifice finger, or sacrifice ruler?) All good now. ;)

Instructions are not in English. It’s all in Chinese language

Quick simple easy perfect for all kinds of things all in one tool. Love it

Easy to use

You get two different templates. One is a full circle with many circles - number marks next to the circles seem to be the radius in millimeters. Full 360 degrees are marked on the outside.The second template have moving parts. it has its own case and instructions showing how to use it. It has metric measurements, and is also useful for geometry class.The templates were made of clear plastic, and it looks like they are fragile, at least they look like my countless clear rulers that snapped while in use, so be careful.The are crystal clear to see what is underneath

The ruler is handy for sketching out ideas. The acrylic is pretty clear. Both the slider and wheel move relatively smoothly. I wouldn't call this professional quality, but it's fine for personal use.
