Excellent delivery but very disappointed with the product.
The colors are great but the material they are made of is very thin and fragile. The protractors are also made in a similar way, and the writing is very small to read. I have already purchased a replacement from another source.
Pros
WIDE APPLICATION. Straight ruler and math protractor as a great protractor for learning math is suitable for kids, teachers, students, office workers, etc. It's much easier for kids to use them when measuring angles in textbooks, worksheets or notebooks. They are small enough to fit within the angle they are measuring.
