Pocket warmers set of 4 – reusable smiley hand warmers

A cold morning. The walk to school drags on, and at the bus stop your fingers slowly go numb. That's when you reach into your coat pocket. A pocket warmer with a friendly smiley gives you cosy warmth, just right for frosty winter days. One click is all it takes. The hand warmer then turns nice and warm in your coat or trouser pocket.

What changes for you

• You have warm hands whenever you need them. A quick click on the small metal disc inside activates the heat pad straight away.
• You don't need a socket or batteries. The gel filling with sodium acetate produces the heat all by itself.
• You don't have to keep buying new ones. Each pocket warmer can be reused by briefly boiling it, up to 500 times.
• You don't carry anything bulky around. At approx. 95 mm in diameter, the heat pad fits into any coat or trouser pocket.
• No squabbles in your family. Four smiley designs in four colours mean everyone gets their own.

Why these hand warmers make a difference every day

The cold makes us impatient. Whether on the way to work, waiting on the sidelines or at the Christmas market. With a hand warmer in your pocket, the cold season feels more relaxed. You leave the house more calmly, because you know warmth is just a click away. And the cheerful smileys bring a smile to people's faces too. Not just children's.

Material & finish

Inside, a gel filling with sodium acetate does the work. This substance is not hazardous. It is even approved as food additive E262. It is used, for example, as an acidity regulator in many tinned fruits, vegetables, fish and salads. So you can give the pocket warmers to children too. The warmth comes quickly and lasts a long time. Gently kneading the pad after activating it makes the warmth last even longer.

How to use the hand warmers

• On the way to school or work: one click before you set off, and your hands stay warm until you arrive.
• On a winter walk or at the Christmas market: a hand warmer in each coat pocket, and you enjoy the fresh air instead of freezing.
• On the sidelines or during winter sports: warm your fingers up for a moment in between, and you're back in the game.
• As a small gift or in an Advent calendar: the four cheerful smiley colours make the set a little present that children and adults alike will enjoy.
• Our tip before first use: Boil the pocket warmers once before using them for the first time. That way you get the maximum warming time right from the start.
• Our tip for when you're out and about: If you can't boil the pocket warmers during the day, simply boil them briefly in the morning before you leave the house. First use the leftover heat from boiling without activating them. You can then activate the pocket warmer on your way home and enjoy the warmth a second time.

Good to know about pocket warmers

There's a little bit of physics behind the click. The sodium acetate solution inside is supercooled. Clicking the metal disc triggers crystallisation. This releases the stored heat. That's why the heat pad works without any batteries. Boiling it returns it to its original state again and again.

Care & durability

There isn't much you need to do. Once the warmth has faded, simply place the pocket warmer in boiling water for a short time. Leave it until the filling is clear and liquid again. After that, it's ready to use once more. This works up to 500 times, so the set will last you many winters.
