No signal until the coffee kicks in.

This coffee phone case turns your energy level into signal bars, made for coffee lovers and anyone who runs on caffeine more than on sleep. Keep the joke for yourself or tuck it into your stack of gifts for coffee lovers.

The design: energy, measured in bars

Caffeine Signal is a minimalist, one-color design built from two parts. At the top sits a signal-strength icon, three curved bars fanning out above a round dot, drawn in solid black with soft grey bevel highlights that give it a slightly raised, 3D look. Below it, CAFFEINE and SIGNAL stack in two centered lines of bold geometric capitals.

There's no background fill behind the art. The icon sits just below the camera, the words follow, and the lower third of the back stays clear, so your phone's own finish shows all around the print. Nothing else is drawn: no cup, no beans, only the icon and its two-word caption.

The joke lands in a second. Everyone knows the little bars that tell you how connected you are; here they measure the caffeine in your system instead, and they only fill up once the coffee does. It's a sharp Caffeine Signal graphic and a quirky conversation-starter for anyone whose mornings don't load without coffee.

Quick answers

Which phones does it fit?

Each case is cut for one iPhone model, and the mini, Plus, Pro and Pro Max versions all differ in size, so choose your exact model in the Size option, which lists every model we make it for. The SE option fits the 2020 iPhone SE.

Will the print show up on a dark phone?

It reads best on a light phone. The print is black and the case is clear, so on a dark phone the bars and words sink into the finish and get hard to read. On white, silver or gold phones the joke reads from across the table.

Is it a rugged case?

No. Nothing about it is armored, and it carries no drop, shock or water rating. Phones that live on work sites, climbing walls or boats are better off in a heavy-duty case.

Is there anything to peel off first?

Take a look inside before you fit your phone: the case may come with a thin protective film on the inner surface. Peel it away first.

Is the icon a company logo?

No. It's original RaZits art built on the familiar signal-strength symbol, with no brand name or company mark. The only words on the case are the two in the caption.
