You glance at your watch.

It’s 6:28. You’ve been at it since 3.
Crap. Your hot date is at 7. Running late. Sink shower it is.
Nowhere close to done editing…

“…at least all the ideas are laid out, so there’s that. Did I miss anything? I don’t think so? Ok, but how do I make it flow? I need to get the final draft to Stacey for design asap, team cutoff is at noon Thursday…”

You’ve spent dinner completely distracted. Your date just took off. You go home exhausted, plod to your desk, and flip open the laptop.

Or… what if:

5:41 — you’re out of the shower and lip-syncing.
6:17 — dressed to the nines and zenned out.
7:03 — the sunset glints off your aviators as you smile hello.
8:36 — it actually feels like you’re hitting it off. Not just hot, funny to boot.
Next morning, 9:27 — final draft ready in your inbox.
10:31 — Stacey messages back, “thanks, looks good!”

The difference?

Copygloss handled it. Before you left for the date, actually.

This 10-Day Test
Has shown millions the way to white teeth

This is how millions have found the way to whiter, safer teeth. You see the results on every hand — perhaps in teeth you envy. Send now for this simple ten-day test and see what you own teeth show.

Why teeth discolor

There is on your teeth a viscous film. You can feel it with your tongue. It clings to teeth, enters crevices and stays. That film is the teeth’s great enemy. It dims them and destroys them.

The tooth brush fails to end it, for the ordinary tooth paste cannot dissolve it. So for months between your dental cleanings it may do a ceaseless damage. 🏁 

One of the most famous long-copy ads ever, from the father of modern advertising himself.

First paragraph: a social-proofed promise, a poke at the ego, then a brief call to action. But the CTA leaves you with unanswered questions — hence you read on.

Second paragraph: time for pain. Sparing no details, let’s dive into how your teeth are rotting away.

And crucially: everything is oriented around “you.”
