It's more than that — 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 effect is real and measurable. The pendant is just the delivery mechanism — one you can wear every day.

Extended exhale breathing is one of the most well-studied techniques for calming the nervous system — used by military, athletes, therapists, and breathing coaches. TOKIN makes it physically easier to do correctly in a moment of stress, without having to remember a technique or open an app.

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.
