Because your coffee deserves better than going cold next to 17 open tabs.

Eggciting looks like a fried egg.

It warms your mug. That’s it. That’s the product.
It plugs into your USB port and gently judges you while keeping your caffeine at a temperature slightly hotter than your patience.

Perfect for anyone who forgets about their drink until it’s room-temp sadness. Also perfect for people who like their desk accessories shaped like breakfast food for no logical reason.

The Man Who Declared War on Beige

I didn’t set out to start a brand. I set out to fix a mood.

Everything around me felt a bit… beige — the products, the offices, the energy. So I decided to build a world where colour, humour, and design could coexist without needing permission.

Mustard was born out of equal parts curiosity and chaos. It’s proof that practicality doesn’t have to be dull, that playfulness can still have purpose, and that good design should make you smile before you even use it.

We make things that stand out on purpose — because blending in is overrated.
