the re-usable hand warmers, when they are in liquid form you click the
metal disc inside the liquid and the liquid then turns solid and hot, to
reactivate them you have to boil them or put them in the microwave (check
the instructions first though as this may not be the case for all
types/brands). The cost about £3 each and you can get them from Ebay and
most sporting/fishing/skiing shops
the disposable warmers, they come in pairs and are also known as teabags,
to activate you open the packet and just shake gently, they react to oxygen
and go hot, they should stay hot for about 7 hours, they are smaller so
can fit into gloves and boots. They are far cheaper on Ebay and you can
get 10 pairs for about £10 including postage, the more you buy, the
cheaper they are.
| They do need a bit of a shake to reactivate them if they
have been active for a while.
