Architectural Tools from Amazon are great!
I found that the price for this item and the fact they had it in stock pretty much forced me to buy it from Amazon vs. a traditional retail brick and mortar seller. Although I feel bad for the other merchant, it was good for me as a customer. This product does the job of creating straight lines with precise measurements. It's a trianble with a protractor, so you can do triangles and circles too and know what angle you are designing. My daughter used this for her Landscape Architecture classes.

Good buy
I bought this for making neat boxes on my notes pages. Works well. I would have preferred to just buy the 1 triangle, but it was still a good price.

Held up whole collage
This set held up better than I expected. I bought it at the start of college and used it heavily throughout my architecture and math courses—lots of drafting, sketching, measuring, and note-taking. The markings and numbers never faded, even with near-daily use, and everything stayed precise and easy to read. The plastic is sturdy, not flimsy like some cheaper ones I’ve seen, and it always gave me clean lines without slipping around. It’s one of those tools I just kept reaching for, and years later, I still have it in my drawer. For the price, the quality is honestly impressive. It did the job well, and then some.

Very useful and versatile, especially for drafting complex 3D polygons
Love it! Perfect and smart placement of parallel rules and angular rules. I use it to draft fairly complicated 3D polygons and other 3D line arts.

Nice and easy to use
These are really handy and easy to use. I got them to use with a dot journal and it has made it easier to make designs & graphs.

Metrics scale not US scale
Didn't know it only came with cm no inch. Shipped from China didn’t know that till I received it. Every country but the USA and three others use the English system most other countries use the metric system. Only reason I gave the low score.
