Design You Can Feel
The Neuro³ Cube is precision-machined from solid 304 stainless steel and softened with a 1mm chamfer, balancing sharp geometry with everyday comfort.
At 1kg, the weight feels substantial — grounding you as much as it cools. Dense mass means superior cold retention, delivering multiple focus resets from a single freeze.
Why 304 Steel?
We chose 304 stainless steel for a reason:
Food-grade and skin-safe — no risk of leaching or chemical coatings.
Corrosion-resistant — won’t degrade, flake, or rust over time.
Superior thermal retention compared to aluminum or glass.
This ensures every session is safe, clean, and consistent for a lifetime.
Fits Any Situation
Professional — a scientific tool at your desk, ready for your next reset.
Gym — a performance aid between sets, restoring endurance without stimulants.
Personal — a modern object that feels as good in your palm as it looks on display.
No caffeine. No crash. Just clarity on demand.
Your palms are more than just skin — they’re one of the body’s primary thermoregulation zones. Beneath the surface are specialized blood vessels called arteriovenous anastomoses (AVAs).
Stanford research has shown that cooling the palms rapidly reduces core body temperature, accelerating recovery and restoring mental clarity. Unlike splashing your face or drinking iced water, palm cooling directly taps into the body’s built-in heat exchange system.
Think about the last time you left the gym overheated or finished a long stretch of deep work — grabbing something cold with your hands brings instant relief. That’s your palms acting as radiators, dumping heat fast. The Neuro³ Cube is engineered to harness that effect on demand.
All Neuro³ Cube preorders are scheduled to begin shipping in November. You’ll receive an email update with tracking as soon as your unit leaves our facility.
Do I pay now or later?
Preorders are charged at checkout to secure your spot in the next batch. This guarantees your unit will be reserved for you.
Can I cancel my preorder?
Yes. You may cancel anytime before your order ships for a full refund. Once your cube is dispatched, standard return policies apply.
How should I use the cube?
Keep your cube in the freezer. When you need a reset, hold it in your palm for 30–60 seconds. The cooling effect works through natural thermoregulation pathways in your hand.
What makes it different from ice?
The Neuro³ Cube is engineered from 50mm heat-treated 304 stainless steel. It holds temperature longer, avoids melting mess, and is designed for repeated daily use.
Review highlights palm cooling as a promising tool for managing thermoregulation under extreme stress.
The Takeaway: Your palms are radiators. Cool them, and your body resets — clarity returns, fatigue fades, and performance continues.
What People Are Saying
Lily, 32, Marketing Manager
I used to get the 2PM office munchies hard. Now whenever I go to grab the chocolate, I grab the cube
Chris, 28, Crossfit Athlete
I used to gas out halfway through. Now between rounds I grab the cube, cool my palms, and it’s like I bought myself another set. Fatigue delays, focus comes back, and I can push through instead of burning out early.
Jordan, Entrepreneur
Late nights used to crush my focus. Now when I cool my palms with the cube, I reset fast and get back into flow.
