Flexi-Curve Rulers

Flexible Curves are of superior quality and excellent for drawing smooth
curves. They have a flexible lead core, surrounded by vinyl which does not
discolour or fragment. Suitable for drawing curves as small as 15mm, marked
in mm’s and cm’s on both sides. Raised edges for ink ruling or pencil lines.
Technical pens, ruling pens and pencils all work well. Create numerous drawings
from dressmaking patterns to architectural plans.
