パズルデザイン描画テンプレート定規

My puzzle drawings finally look professional with this ruler—the 20cm length is perfect for creating consistent grids. The slots keep my pen from slipping, which was my main problem before.

The precise measurement markings are really clear and easy to read against the white plastic. I used it to draft a simple maze for my kid and the straight edges made the lines perfectly even. It's a nice little tool for anyone who enjoys geometric doodling.

The 20x10cm size fits perfectly in my sketchbook pocket, and the clean cutouts let me trace crisp puzzle shapes without any slipping. I’ve been using it to plan a jigsaw-themed card design, and the assorted colors in the pack add a nice variety.
