Space blankets - where can I get them from?

[chonky]

Help - Rompa have stopped selling 'space blankets' (the silvery blankets you get given after the marathon or when you're about to keel over from hypothermia). DD LOVES them. Anyone know where I can buy them? I can't buy them from Milletts or Blacks, as the foil comes off which doesn't seem a particularly healthy thing for dd given the amount of time she spends mouthing them.

If you Google 'survival blankets' quite a few come up, ranging in price from £2.50 upwards. Otherwise have a look in small independent pharmacies, as they are often in a first aid kit.
