PENPAI 4-Piece Flexible Ruler Set | 20cm Ruler, Protractor and Triangles | French Curve Stencil

A shatter-resistant Penpai 4-piece drafting set with a 20cm ruler, protractor and two triangles, plus a bonus French curve built into the 60° triangle.

• 4 tools in one kit: 20cm ruler, protractor, 45° triangle and 60° triangle cover standard drafting needs
• Bends without breaking: Flexible, shatter-resistant material holds up to everyday classroom use
• Two measurement scales: Metric (cm) and imperial (inch) markings on the same tools
• Bonus French curve stencil: Built into the 60° triangle for drawing smooth, curved lines
• Clear for accurate work: High-transparency design makes alignment and reading easy

This 4-piece drafting set covers the core tools needed for geometry and technical drawing: a 20cm straight ruler, a full 0-180 degree protractor, and two triangle set squares at 45 and 60 degrees. Rather than buying each tool separately, everything ships together in one shatter-resistant, flexible set that bends instead of cracking under pressure. A useful extra is built into the 60-degree triangle: a French curve stencil along one edge, which makes it possible to sketch smooth, curved lines without a separate curve template. All four pieces carry both metric (cm) and imperial (inch) markings, and the high-transparency plastic makes it easy to see the page underneath while aligning a line or angle. It's a practical, all-in-one option for students or hobbyists who need a complete, durable measuring and drafting kit rather than individual pieces.
