Dutch supermarket giant Albert Heijn has launched a blue phone case with a built-in eierdopje (egg cup) on the back — and no, before you ask, it is absolutely not an April Fools’ joke.

When the supermarket posted a slick promotional video for the gadget, followers were unconvinced. “This can’t be real,” came the replies, alongside “April 1st is early this year.”

However, an Albert Heijn spokesperson confirmed to AD that it’s the real deal: “We understand people think that, but it isn’t the case.”

The video’s mysterious voiceover laments that technology has long tried to bring people together, but keeps driving them apart — especially at the breakfast table.

The solution? Strapping an egg cup to your phone. Perfectly normal.

Commenters seemed genuinely won over, with egg puns flying fast: “Egg-cellent,” “Finally the innovation we needed.”

We’re not sure the Nobel Prize committee is ready, but we respect the hustle.

Buyers have already found creative uses beyond balancing a soft-boiled egg on their handset.

The little cup reportedly doubles as a sauce dish, a shot glass, and even a suction mount for the car — making it the most versatile piece of technology since the Swiss Army knife — if Swiss Army knives were blue and smelled faintly of breakfast.

If you missed Albert Heijn’s previous foray into unexpected merch, this tracks perfectly. The Dutch supermarket has serious form.

Still doubting if it’s an April Fool’s grapje? Well, AH is committed to the bit, so the phone case is available on Albert Heijn’s website.
