The temperature, published honestly

Bis zu 12 Stunden anhaltende Wärmepads mit einer durchschnittlichen Temperatur von 55 °C.

An average, not a peak.

Seven warmers on this shelf. Two publish a temperature and this is the one that says which kind of figure it is.

What is inside

Eisenpulver, Wasser, Salz, Aktivkohle und Vermiculit.

Iron powder, water, salt, activated carbon, vermiculite.

The iron rusts when the packet is opened and rusting gives off heat; the salt speeds it, the carbon spreads it, the vermiculite holds it. That is the whole technology of a disposable warmer, and two listings on this shelf name it.

The size

9.5 × 5.5 cm — half a centimetre larger in each direction than the neighbour that also publishes one.

Three pack sizes

5, 10 or 30 pairs. The reference read here is the ten.

The shelf life

Ungeöffnet mehrere Jahre haltbar. Several years, unopened.

The price across five stores

13.99 in Britain. 14.99 in Germany. 18.99 in Spain. 19.99 in France and Italy. The American store does not carry it.

Availability

One check, 15 € at the bottom and 20 € at the top, across the German, French, Italian and Spanish Amazon shops.

Outside the euro, the British Amazon shop sells it in its own currency, and the range above is kept clear of that.

An empty answer from the American Amazon shop: the buy button there opens a search instead of a blank page.
