## Customer Reviews

### ⭐⭐⭐⭐⭐ Best Price and Quality
*by B***L on June 14, 2017*

I needed this set for a small art project I had. I mainly got it because it had the best price. I am impressed with the quality of the set.It comes with large right triangles (set squares) and a triangular scale. All 3 pieces are of high quality. The set squares are thick, and hard to break. They are 30-60 and 45 degree triangles. The 30-60 one is graduated 11"x6" and the 45-90 one is graduated 8"x8". There is a protractor in the middle of 45-90 triangle which is pretty cool.The scale is also very sturdy. It will not break. It seems like the prints on it are permanent. It's an architectural scale and it's in imperial units.Over all I am very happy with this product and I recommend it to others also.

### ⭐⭐⭐⭐⭐ Great drawing set.
*by J***S on September 16, 2024*

It is easy to handle. I wish the comps were a little larger.

### ⭐⭐⭐⭐⭐ Handy Set
*by A***R on August 14, 2025*

This handy set has what I need to draw up plans on my grid paper. The tools are easy to read and a nice size for working on standard size paper.
