£4.65 with p&p 550ml stainless steel mug with metal lid
http://www.ebay.co.uk/itm/Home-Silve...item45fc42bed6
I ordered one of these a while back and it turned up today.
The cup is definitely not 550ml as advertised more 400ml i.e. a "normal" sized tin cup whereas I was expecting a slightly oversized one.
Quality is okish , inside is a matt finish.
The lid is the most useful bit as it fits a number of other bigger containers which could be used for boiling water/cooking. The knob is plastic but fit on with a screw so you could replcace it with something a bit less combustible if needed.
If anyone is interested I can post up some pics.
