Hot water bottle hand warmers, set of 4 – matt red

The walk to school in the dark, the Sunday winter stroll, waiting at the bus stop – and your fingers go numb despite your gloves. A pocket warmer shaped like a hot water bottle helps within seconds. You bend the little metal disc inside. Cosy warmth then spreads through your coat or trouser pocket. The set of 4 in matt red is made for the cold season. There is one hand warmer for you and enough to share with the whole family.

What changes for you

• You have warm hands exactly when you need them. Bending the metal disc is all it takes, and the warmth starts straight away.
• You don't need a socket or a rechargeable battery. The hot water bottle hand warmer works without batteries or any other power source.
• You can use each pocket warmer again and again. Boil it briefly and it's ready to use once more – up to 500 times.
• Just pop it wherever there's room. At around 11 cm tall, it fits in any coat or trouser pocket.
• You can make the warmth last longer by gently kneading the activated warmer.

Why these hand warmers make a difference every day

Cold hands can quickly turn a lovely winter's day into a slog. With a small heat pad in your pocket, you leave the house more relaxed. The way to work feels shorter. The walk can last a little longer. And because the set has four hot water bottle pocket warmers, everyone in the family can carry their own.

Material & finish

The surface is matt and offers a good grip. So the pocket warmer won't slip out of your hand, even with cold or gloved fingers. The slightly transparent red material lets the gel filling show through. When you activate it, you can watch the crystals spread. The sodium acetate filling is safe. The substance is even approved as food additive E262. So you can carry the hand warmers in your trouser pocket or give them to children for the walk to school.

How to use the hand warmers

• On the way to school or work: bend the disc at your front door – and you arrive with warm hands instead of numb fingers.
• On a winter walk or at the stadium: one hand warmer in each coat pocket, and the cold is much easier to bear.
• At the market stall or on delivery rounds: if you work outdoors in winter, you can warm your hands in between. No power, no fuss, again and again.
• As a small gift: there are four in the set. Keep one for yourself and give three to people you'd like to treat in winter.
• Our tip before first use: Boil the pocket warmers once before using them for the first time. That way you'll get the maximum warming phase right from the start.
• One more hot tip for when you're out and about: If you can't boil the warmer during the day, do it in the morning just before you leave. First use the leftover heat from boiling without activating the pocket warmer. That way you save the activation for the journey home and get the warmth twice.

Good to know about sodium acetate

Sodium acetate, the filling of these pocket warmers, is more common than you might think. As acidity regulator E262, it's found in many tinned fruits, vegetables, fish and salads. This is what makes the warmers so practical for everyday use. You can carry them close to your body and give them to children too.

Care & durability

There isn't much to do. Once the warmth has faded, boil the pocket warmer briefly until the filling is liquid and clear again. It's then ready to use once more – up to 500 times. So the set will see you through many winters, with no batteries to buy.
