What is UNIHAND

UNIHAND is a hand warmer brand with one product. We make a rechargeable pair of pebble-shaped warmers that you can carry apart or join into one, in ten colors, for the cold stretches of your day.

What we make

Our whole range is a single pair. Each box holds two warmers and a USB-⁠C charging cable, and every warmer has a lithium battery inside, an orange button on its face and a row of three small lights. You charge it, switch it on, and it warms your hands for the walk, the round or the long sit ahead.

We kept it to one product on purpose. One shape, one set of heat levels and one way of charging means you learn the warmer once and never have to relearn it, whichever color you carry. It also means everything we know goes into making that one pair easy to live with.

Our store banner puts the idea in a line we still like: A warm life, a refined existence. In plainer words, we want you to feel warm and comfortable in the cold seasons, without fuss and without throwing anything away at the end of the day.

Two warmers that become one

Most hand warmers are a single unit or a pair of packs. Ours are two rounded, symmetrical pebbles, each 3.46 inches long and 0.79 thick at about 0.15 lb, small enough for the front pocket of your jeans.

You can use them three ways. Keep one in each pocket and both hands get warm in turn. Give one to the person next to you, at a game or on a cold platform. Or set the two back against back, and they become a single warmer the size of your palm with heat on every side. We call that 360-degree warmth, and the whole idea the 2-in-1 design.

Each unit has its own battery, so one can work while the other waits switched off. That gives you a second shift of heat on a long day, or a warmer for a friend who forgot gloves.

What we call the AI chip

Inside each warmer is a temperature sensor and a controller. We call it the AI chip. It keeps track of how warm it is between the shell and your palm. Then it adjusts the heat to stay at your chosen level as the air around you changes.

That matters most on days that change under you. You step from a warm car into a wind off the lake, or sit down after a long walk. The warmer keeps working toward the same range instead of drifting with the weather.

It does not learn your habits, choose a level for you or do anything for your circulation. You pick Low, Medium or High with the button. Low holds 95-⁠107.5 °F, Medium 104-⁠118.5 °F and High 118.5-⁠130 °F, and the chip keeps you there. Our heat levels page gives the up-to hours for each.

Ten colors

The warmer is the same inside every shell, and the shell comes in ten colors. There are four darker ones, Black, Dark Green, Blue Grey and Bronze, and two light ones, White and Champagne. Pink, Purple, Sky Blue and Mint Green make up the softer four.

We offer that many because a warmer is something you hold every cold day, and people care how it looks in their hand. A box is one color, so a household can give each person their own. You can compare all ten on our colors page or see them together on the hand warmers collection.

Where the pair goes

UNIHAND has been making hand warmers since 2022. We make the pair for the places winter catches your hands: golf courses and deer stands, ski lifts and campsites, offices, lecture halls, stadium seats and the walk to the train. And because the box holds two, it makes an easy present for Christmas or a winter birthday.
