When building scale models or Gunplas, we often have to make equidistant markings or holes. They may be needed to engrave panels, simulate rivets, or install conduits, fairings, etc.

If we are doing it over a curved surface like a plane fuselage, the body of your Gunpla, a tank turret... we cannot use a regular ruler.

These flexible solutions conform to any curved surface, and they come in two models: with a flat edge, or a curved one.
