How it works

Longer exhales activate your body's natural calming response — TOKIN makes it effortless.

01

Breathe in

through the nose, naturally

02

Exhale slowly

through TOKIN — let the resistance guide you

03

Repeat

Three breaths. That is the whole method.

The evidence

Slow, extended exhales are among the most studied techniques for calming the nervous system. A few of the findings.

5 minutes

In a Stanford study of 114 people, five minutes of daily exhale-focused breathing improved mood more than mindfulness meditation. The difference was a longer exhale.

Balban et al., 2023 — Cell Reports Medicine

24 studies

A meta-analysis of 24 studies found slow-paced breathing produced a significant reduction in self-reported stress and anxiety.

Goessl et al., 2017 — Psychological Medicine

6 breaths a minute

At around six breaths per minute, heart rhythm and breath fall into sync — what researchers call resonance. Slow breathing at this pace has been shown to lower blood pressure and improve the body's own pressure regulation.

Research on resonance breathing

TOKIN is a tool for guided exhale breathing. It is not a medical device and does not diagnose, treat, or cure any condition.

The story behind TOKIN

Built from
experience.

Cam Cairnduff

Founder, TOKIN

Cam experienced panic episodes. The kind that feel like your world is closing in. Like losing control of your own body.

He needed something simple. Physical. Immediate. Not an app. Not a breathing course. Just a tool that worked, right now, in the moment.

So he built TOKIN.

"Because sometimes you don't need more information. You need something that works."

— Cam Cairnduff, Founder

Questions

Everything you're wondering before you buy.

This is a pre-sale for the first run of 300. Orders ship in the order they were placed, tracked and free within the UK, as soon as the run arrives. I will email you with a confirmed date the moment the factory confirms it — and if the final prototype fails quality assurance, every pre-order is refunded in full.

£39 is the pre-order price and it is held for everyone who orders before launch — £49 after. There are no discount codes and there never will be. The price is the price. TOKIN is made in small batches by an independent founder, and this is the first run of 300.

No. TOKIN is a wellness tool that makes slow exhale breathing easier to do. It is not a medical device and is not a substitute for professional care. If anxiety is interfering with your daily life, a doctor or licensed therapist is the right first step — TOKIN works alongside that, not instead of it.

TOKIN is precision-engineered to create a specific resistance that encourages a slower, longer exhale. Slower exhales activate the vagus nerve, which triggers your body's natural parasympathetic response. The shape does the work — one you can wear every day.

Extended-exhale breathing is one of the most well-studied ways to calm the nervous system. TOKIN makes it physically easier to do in a moment of stress, without having to remember a technique or open an app. TOKIN is a wellness tool, not a medical device. It is not a treatment for any medical condition.

It looks exactly like a pendant necklace — because it is one. Nobody will know it's anything other than jewellery unless you tell them. That's the whole point.

Every pre-order comes with a 30-day guarantee: full refund — and you keep the pendant. If TOKIN doesn't help you, email us within 30 days of delivery and we'll refund you in full.

When you're anxious, you're not thinking clearly enough to pace your breathing well. TOKIN gives you something physical to focus on — the act of finding it, raising it to your lips, and exhaling through the resistance anchors you in the present moment. It also ensures the exhale is the right length automatically.

Medical-grade 316L stainless steel. The same material used in surgical instruments — hypoallergenic, rust-resistant, and built to last. Easy to clean with warm water.
