How it works

One click.Instant heat.

No power. No microwave. No flame — just a clever bit of chemistry you can hold in your hand, and reuse for years. Here's exactly what's going on.

The science

It's all in the click.

Inside every pack is a food-grade gel — supersaturated sodium acetate — and a small stainless steel disc. The liquid is holding more warmth than it should, just waiting for a reason to let go.

Flex the disc and you give it that reason. The gel crystallises in a chain reaction and releases its stored heat instantly. Drop it in boiling water later and the crystals melt back to liquid — ready to click all over again.

Heat therapy

Warm in seconds.

01 Click the disc

Click the disc

Flex the metal disc inside the pouch with your thumb. One firm click — it's oddly satisfying.

02 Watch it turn white

Watch it turn white

The gel warms from clear to soft white, spreading out from the disc through the whole pouch.

03 Put it where it hurts

Put it where it hurts

Within seconds it warms to a gentle, soothing heat — up to around 54°C, depending on the room. Tuck it against a sore back, belly, shoulder or knee.

04 Reset for next time

Reset for next time

Once it cools, simmer it in boiling water for 10–15 minutes (timed from when the water is boiling). The gel clears and it's ready to click again.

Cold therapy

Cool when you need it.

01 Pop it in the freezer

Pop it in the freezer

Lay the pack flat in the freezer for a couple of hours — no need to click the disc for cold.

02 Wrap it and apply

Wrap it and apply

Wrap it in a thin cloth and hold it to a fresh strain, a bruise or any swelling.

03 Back in the freezer

Back in the freezer

When it warms through, return it to the freezer. Same pack, same routine, whenever you need it.

Turned white in the freezer? That just means it’s activated by accident — pop it in boiling water to reset and it’s ready to use again.

Good to know

The practical bits.

Gentle heat A gentle, safe warmth — never scalding. How warm it feels depends on the pack size and the room. Over clothing for sensitive skin.
Long-lasting Of soothing heat per activation, depending on the pack size and the room.
Reusable Boil to reset and reuse — again and again, for years.
Hot or cold The same pack clicks for heat or freezes for cold therapy.
No power No cords, no microwave, no flame. It runs on chemistry alone.
Instant One click and the pack warms to soothing heat in seconds — no waiting, no warm-up.

Common questions

It stays at a gentle, soothing warmth — warm, not scalding — and how warm it feels depends on the pack size and the room. If your skin is sensitive, rest it over a layer of clothing.

Again and again. Once it cools, just boil it to reset and it's ready to use all over again.

No. Packs activate by flexing the disc, not by heat. Boiling water is only for resetting — microwaving can damage the seal.

It depends on the size of the pack and how warm the room is — the bigger packs stay warm for a good while. Boil to reset whenever you need it again.

Yes. Click the disc for instant heat, or lay it in the freezer for cold — one pack does both.
