These aluminium multiple rulers are pretty awesome. They have a super smooth open-close mechanism that is a joy to use (and pretty addictive). The ruler itself is constructed from high grade aluminium and features a 30cm laser engraved scale which will stand the test of time without fading. Folds down to half its size - just 15cm.
