Review on 🔺 Alvin SK360-12: 12-Inch Smoke-Tint Triangle Ruler - Math Geometry Tool (30/60 Degrees) by Kristen Simpson

I haven't done much by hand in the last few years, but I still have everything I need. The last time I actually did most of this work I bought a 45 degree smoked Alvin triangle at my local art supply store. I liked how it works with ink as the chamfer prevents smearing of ink that might get under the edge of the triangle. A few years later I finally got around to buying 30-60-90. It actually matches my older 45, both in hue and relative size. I am very happy with it and look forward to more design work!
