Pacific Arc - Topaz Triangles

Topaz Triangles

Draft precise technical drawings with edges that stay razor-sharp for years

Thick acrylic construction means these triangles maintain crisp edges through years of heavy use, no feathering, no breakdown from repeated pencil or pen contact. Pacific Arc machines each Topaz triangle from solid acrylic stock rather than stamping thin sheets, creating beveled inking edges that hold technical pens, ruling pens, and graphite at the proper angle to prevent ink bleeding and smudging. The subtle amber tint makes these triangles easy to spot against white paper or dark cutting mats without obscuring your work underneath.

Cut-out finger lifts let you grip and reposition quickly during complex layouts, while generous thickness provides stability that prevents flexing mid-stroke. Both 30/60 and 45/90 configurations feature precisely calibrated angles that maintain accuracy whether you're constructing perspective drawings, establishing grid systems, or checking alignment across large format work. The beveled edges accommodate everything from 0.1mm technical pens to soft graphite without dragging or catching.

Architects and technical illustrators appreciate how these triangles bridge the gap between student-grade plastic that warps and professional metal triangles that cost three times as much. The acrylic resists solvents and won't yellow with age or exposure.
