Cold hands no longer interrupt what you’re doing
Warm hands on demand — activated by flexing a metal disk, heats up to 129.2°F for about 45 minutes, reusable up to 300 times without disposable replacements
Why Is This Perfect for You?
✔ Heat when needed: Flex the small metal disk to trigger a heat-producing reaction in the liquid pouch. It warms up to 129.2°F and provides about 45 minutes of heat, or longer when kept in a pocket.
✔ Reusable up to 300 times: Reset the warmer by boiling it in water for about 10 minutes, until the crystals turn back into liquid. Reusing it helps reduce disposable warmer waste.
✔ Compact warmth outdoors: Keep it in a jacket pocket to warm cold hands while hiking, bird watching, or working outside. It can also help dry wet shoes; place a layer of fabric between the warmer and skin during prolonged contact.

Frequently asked questions
The things people ask before ordering. Everything else is on our FAQ page.
When will my order arrive, and what does delivery cost?
Orders arrive in 4–12 business days — 1–2 days processing, then 3–10 days in transit. Shipping is free on every order, with no minimum spend, anywhere in the United States.
Where do I find my tracking link?
In the dispatch email we send when your order leaves us. Tracking becomes active 1–3 business days after dispatch, so no movement straight away is normal. You can also check our order tracking page.
What if a piece isn't right for the room?
You have 30 days from delivery to send it back. Email us for a return authorisation first. Items must be unused and in their original packaging, you cover return postage on change-of-mind returns, and refunds are issued within 5–7 business days of arrival.
What happens if something arrives damaged?
Tell us within 48 hours of delivery with photos of the piece and its packaging. We replace or refund it, whichever you prefer, and cover all postage — you are never out of pocket for our mistake.
Which payment methods do you accept?
Visa, Mastercard, American Express, Discover, Diners Club, PayPal, Shop Pay, Apple Pay and Google Pay. Prices are in USD, tax is calculated at checkout, and we never see or store your card details.
