The Nemuri Breathwork Necklace - Relaxation On Demand
THE NEMURI 3D PENDANT
The Nemuri Pendant is the world's first wearable Vagus Nerve stimulation device to be fully 3D printed. It requires no batteries, no Bluetooth, no app, no firmware updates, and no charging cables. You simply breathe through it — and that's the whole point.
The internal channel is geometrically tuned to add a precise amount of resistance to the air on the way in and the way out. That tiny resistance is what does the work. It naturally lengthens your exhale, slows your breathing rate down into the parasympathetic-dominant zone (around 4–6 breaths per minute), and gently activates the diving reflex through the soft pressure feedback you feel as you breathe. Within a minute or two of use, most people report a noticeable drop in their shoulder tension and a softening behind the eyes.
It's perfect for learning how to properly stimulate your Vagus Nerve safely and easily — all while sporting a stylish metal of your choice, from Rose Gold, 18k Gold, or Silver.
You can also order it in our NEW Transparent Model!
We encourage you to include a "Black Satin Cord 30 inch" with your order from our online webstore. The option is to "Add a chain" and you have options on what Shapeways will ship to you. For $2 you can add a 30 inch length of satin necklace string. *Recommended!*
WHY WE BUILT IT THIS WAY
If you've spent any time looking at "vagus nerve devices" online, you've probably noticed that almost all of them are battery-powered, app-connected, and surprisingly expensive. Some of them work well, some of them don't — but every single one of them adds another layer of dependency to a process that, biologically, doesn't actually need any electronics at all.
The vagus nerve has been in the human body for hundreds of millions of years. The single most reliable way to activate it is one your ancestors already knew: change the way you breathe. Specifically, slow your breathing down, lengthen your exhale relative to your inhale, and add a small amount of resistance so that the chest, diaphragm, and throat have to engage gently to move the air. That's it. That's the protocol.
The Nemuri pendant is a physical, jewelry-grade implementation of that single insight. No batteries to die. No firmware to update. No company servers to disappear. Just a beautifully shaped piece of metal you wear around your neck that, the moment you put it to your lips and breathe through it, does exactly the thing your nervous system has been waiting for.
HOW TO USE IT
There's no instruction manual because the device is its own instruction. Lift it up to your lips, close them around it, and breathe through it slowly and naturally. Most people fall into a 4-second-in / 6-second-out rhythm within the first few breaths. After about 90 seconds, you'll feel the shift — a softening in the chest, a longer exhale, a quieter mind. If you want to go deeper, extend the exhale even longer than the inhale and let your shoulders drop on each out-breath.
Three sessions a day of two to five minutes each is more than enough to start retraining your baseline breathing pattern. We have clients who use it before meetings, during commutes, on flights, before sleep, after intense conversations, and during recovery from workouts. It's quiet, it's discreet, and nobody around you needs to know what you're doing.
LINKS TO PURCHASE
Our partner service, Shapeways, prints and hand finishes each 3D print right here in the USA. Each piece is inspected, polished, and shipped directly to you. Lead times vary by metal — the polymer / transparent models are typically the fastest, while the precious metal versions take a little longer because of the additional finishing steps.
CARE & MAINTENANCE
Cleaning is simple. Rinse the inside of the channel with warm water after each use, and once a week soak it for a couple of minutes in a mild soap solution before rinsing again. For the precious metal versions, a soft jewelry cloth will keep the outside polished. Avoid harsh solvents and ultrasonic cleaners.
Because there's nothing to break — no electronics, no seals, no battery compartment — a Nemuri pendant should last you for life with basic care. We've had clients still using their original pieces from our first production run, which is exactly what we wanted: a device that becomes a permanent part of your daily nervous-system practice instead of another product you eventually replace.
SUMMARY
We know you are going to absolutely love your Nemuri Pendant. We spent months iterating on the internal geometry, the wall thickness, and the mouth-end ergonomics until the breath felt exactly right. It is, in our slightly biased opinion, the most beautiful and most durable expression of vagal breathwork that you can wear on your body.
It also makes a fantastic gift for a loved one who wants a discreet way to manage stress while at home and out in the world. We've heard from people who bought one for an anxious friend, a grieving family member, a high-strung co-worker — and in each case, the response is some version of "I had no idea something this simple could feel this good."
If you've been searching for a way to bring your nervous system back to baseline that doesn't require an app, an account, a subscription, or a charging cable, the Nemuri Pendant is for you.
We hope you enjoy the Nemuri 3D Printed Pendant!
