Hot-water bottle hand warmers – set of 8 pocket warmers

The walk to the bus stop, hands deep in your coat pockets – and still the cold creeps into your fingers. This set of 8 pocket warmers is made for exactly these moments. They are small hand warmers shaped like hot-water bottles. You simply pop one in your pocket and activate it with a click when you need it. A hot-water bottle with hand-warmer comfort for your coat pocket – and your winter walk instantly feels friendlier.

What changes for you

• You have warm hands whenever you need them. One click of the small metal disc inside is all it takes, and the pocket warmer heats up to 50°C.
• You don't depend on a socket or a battery. The warmth is produced without batteries or any other energy source.
• You don't have to keep buying new ones. Every hand warmer is reusable. A short boil makes it ready to use again, up to 500 times.
• You can kit out the whole family. The set comes in eight colours, so everyone can spot their own warmer at a glance.
• You don't have to look after them. The pocket warmers need no maintenance and are always to hand in your coat or trouser pocket.

Why these hand warmers make a difference every day

Cold fingers turn every walk to school, every wait on the platform and every stroll round the Christmas market into a test of patience. A small heat pack in your pocket changes that straight away. You reach in, feel the warmth and can simply enjoy your time outdoors instead of cutting it short. "Let's get home quickly" becomes "let's stay a bit longer".

Material & finish

Inside is a gel filling with sodium acetate. This substance is completely harmless and is even approved as food additive E262. The transparent outer material with Kawako print lets the eight colours shine. It also shows how the pocket warmer works. When activated, the gel crystallises and gives off quick, long-lasting warmth. Kneading it gently after activation makes the warmth last even longer.

How to use the hand warmers

• On the way to school or work: one click as you set off – and your hands stay warm until you arrive.
• For winter sports: the little pocket heater sits in your jacket and keeps you warm while you wait at the lift. You don't have to take your gloves off.
• At the Christmas market: a warmer in every coat pocket – and your evening in the fresh air can go on a little longer.
• At your desk: a small heat pack for stiff, cold fingers when working from home or in a chilly office.
• At work: for market stalls, delivery services or outdoor areas. Eight reusable hand warmers to equip your team on cold days.
• 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 them 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 click for the way home and enjoy the warmth twice.

Good to know about sodium acetate

Sodium acetate is approved as food additive E262. It is used as an acidity regulator in many tinned fruits, vegetables, fish and salads. So you can give the pocket warmers to children for the walk to school. Or pop them in every pocket for sledging and hiking.

Care & durability

There's not much you need to do. Once the warmth has faded, briefly boil the pocket warmer until the gel is clear and liquid again. Then it's ready to use once more. This works up to 500 times, with no maintenance or spare parts.
