The Merangue Folding Ruler will do the job, but with a few minuscule annoyances. The plastic feels brittle and is easy to crack if you are the type to put too much pressure on it. While the ruler does fold nicely to be merely 15 centimetres, the folding hinge mechanism makes it so that the ruler is not completely level on top, which can potentially make it so that it can be somewhat difficult to get straight lines while using the ruler. Overall a decent product.
