黒の斜像 三角定規コンポジション

The matte black finish blends right into my desk setup, almost like a piece of decor rather than a tool. It’s surprisingly sturdy for its slim profile, and the triangular shape feels satisfying to hold during quick measurements.

I wasn't sure how a black triangle ruler could look elegant, but the sleek design really blends in nicely on my desk. It’s subtle and functional for drawing angles.

The matte finish on this black triangle ruler feels really premium and doesn't pick up fingerprints like my clear plastic ones did. I've been using it to sketch out geometric patterns for my bullet journal, and the dark color makes it stand out nicely against white paper.
