where can I find heated shoulder things?

I remember seeing somewhere these pads that you could heat in the microwave and put round your shoulders.

I was thinking of getting one for my dad as he's got athritis in his shoulders.

Can you get unscented ones?

Unscented wheat bags of various shapes - that the sort of thing?

That's fantastic. Its just what I was looking for. Thanks.

they look good - when they are heated up how long does the heat last for?
