How to use

Secure the lead in the lead part and adjust the compass legs to the desired radius. Place the pointed end at the circle center and rotate the compass smoothly to draw a clean circle.

Recommendations

For consistent results, tighten the hinge moderately to avoid slipping but allow smooth rotation. Replace worn leads with original-sized leads stored in the included lead box, and carry the compass in a protective case to prevent bending or misalignment.
