Rulers
Multi-functioning rulers will accurately measure short distances and assist in drawing neat lines with the characteristic straight edge the instruments provide. Featuring standard calibrated divisions, the line gauge inscriptions accommodate metric, English, or both scale users. The various durable materials used to manufacture the tools will withstand heavy everyday use and may have different levels of flexibility. The clearly marked rulers provide concise size or distance assessments in any environment needed.
