# One line on an egg box was true of a million boxes

> An egg box carries a printed line true of the whole run and a stamped line true of one delivery only. The gap between the two is the whole point of a best-before date.

Six domes, seen flat from above. SIX LARGE is printed across the lid — moulded in with everything
else, true of every box like it. BEST BEFORE 26 AUG sits underneath in blue, stamped on afterward.

A small code runs below that: 3 VRN 44219. Nobody buying eggs is meant to read it. It isn't for them.

## Why does an egg box carry two different kinds of print?

Because one line was true before the eggs existed, and the other only became true once they did.

SIX LARGE describes the box's design — moulded into every unit off the same production line,
whether it ever holds an egg or not. BEST BEFORE 26 AUG describes this box's contents specifically,
added after the eggs went in, on a machine that stamps rather than moulds. The lid is carrying a
fact about a product and a fact about this specific delivery, in two different inks, because they
were written at two different moments.

## Why is a best-before date manufactured to expire?

Because it's the one object in a kitchen made to become wrong on a schedule, on purpose.

Almost everything printed in a kitchen — a recipe, a scale, a wrapper's measuring lines — stays
true forever. A best-before date is deliberately built to stop being true, because the thing it's
describing is a food that's actually ageing while the box sits on a shelf. It's less a fact than a
countdown, printed at the moment somebody had to guess how long that would take.

## What is the small code actually for?

Telling an inspector which farm and which day, in case anything about this delivery is ever in
question.

That string of numbers and letters isn't decoration and it isn't for the person cooking breakfast —
it identifies where and when a specific delivery was produced, so it can be traced backward if it
ever needs to be. Most of what's printed on the box is aimed at a shopper. This line is aimed past
them, at whoever might need to ask a question later.

## Can I put a real farm's code or date on this?

No — and this is the one hard no in the whole tradition, worth stating on its own.

A best-before date, a packer's code and a health mark aren't decoration somebody can license you to
use; they're regulated statements a producer makes about an actual delivery of food. Printing a real
one on a shirt isn't a rights question at all — it's a false claim about food that was never yours
to make claims about. The date, the code and the mark on this design are invented for exactly that
reason, and they stay invented no matter whose egg box the shirt is describing.

## Does the rest of the box belong to anybody?

The wording SIX LARGE and the box's shape don't; a real producer's branding does.

Grading terms and moulded pulp packaging are industry conventions, not anybody's property — every
farm's boxes say some version of the same thing. A specific brand's printed logo or carton design is
theirs, and licensable the usual way if putting a real one on a shirt is the actual point.

## Does this apply to other food packaging?

Anywhere a printed fact and a stamped one share the same box.

A milk bottle's cap carries a use-by date stamped over its printed branding the same way, and a loaf
of bread's twist-tie colour does a version of the same job with no words at all. The [wrapper that
measures butter by where you cut it](/stories/butter-paper-weights) is the same family of
object from the opposite angle — packaging carrying information nobody had to add by hand. A
[freezer lid with nothing on it but a question mark](/stories/freezer-leftovers-labels)
is the failure this whole system exists to prevent: a container with no date on it at all.

## Isn't a best-before date too mundane a thing to notice?

Only if you assume it says the same thing every time, which is exactly what it doesn't do.

Every other line on the box was true the day the mould was made. This one was true on one specific
day and starts counting down the moment it's printed — closer, in spirit, to [a preserve label
numbered 7 of 9](/stories/jam-jar-label-and-date) than to anything else on a supermarket
shelf: both are honest about belonging to one delivery and not the next.

## Does it print well?

Yes — the moulded dome texture, the printed wordmark and the stamped date are three distinct
textures that separate cleanly on fabric.

Keep SIX LARGE crisp and dark, hold the stamped date to a single blue so it reads as added rather
than designed, and set the small code legibly rather than true to scale — an egg box's fine print
disappears at shirt size unless it's drawn larger than the original.

## How do I get one made?

Describe the box at [JustOG](/) — the grading line, the date, and how much of the code to include.
Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to
order and shipped.

Designs other people have published are in the [shop](/shop).

SIX LARGE will be true of the next box off the line. BEST BEFORE 26 AUG never will be, again.
