Each One

It means “each one” or “per item.”

In Spanish price labels, ℆ marks the amount for each item. It abbreviates cada uno or cada una (“each one”), chosen to match the noun’s grammatical gender; c/u is the slash form.

Spanish trade manuscripts used commercial slash shorthand: to save room, writers made the letter before the slash smaller and raised it. Related forms include c/ for calle (“street”) and c/c for cuenta corriente (“current account”). As of 2026, c/u remains handwritten; ℆ encodes it as one character.
