Heart shape promotional hand warmers - UK hand warmers come no sweeter;. perfect for love themed promotional campaigns, be it Valentines Day or not. Printed heart shaped hand warmers are available with single through to full colour print and of course we offer red coloured solution as a further option. We manufacture these heart shaped beauties right here in our Dorset factory; exceptional quality and short lead times as standard.

The magic heat?

No secrets! Our hand warmer heat simply boils down to basic chemistry using salt. We heat up (pharmaceutical grade) Sodium Acetate in purified water. That heat lies dormant in the pack up until the activator disc is snapped causing the tiniest of sparks – which in turn causes the salt crystals to come back together releasing all the lovely warm energy. 100% safe, non-toxic and harmless.

How hot and how long?

On activation, hand warmers heat to 53* degrees centigrade and stay warm for 30 minutes or more depending on the surrounding temperature.

Reusable hundreds of times - simply place back into simmering water for 10-15 minutes.
