Two upward arrows beside a package outline, fixing its orientation.
Also known as: Up arrows
Two upward arrows tell a handler which way up a package must stay. It is the most reproduced handling mark there is, and the one most often applied to boxes whose contents do not care.
In the ISO 780 handling series, two vertical arrows indicate the upright position of a distribution package.
Contexts: Packaging
Printed on packages whose contents have no orientation requirement at all, which weakens the mark where it genuinely matters.
Contexts: Packaging
Two upward-pointing arrows of equal height side by side, each with a triangular head, set above a horizontal baseline.
Both are used in packaging contexts.
