Seems a small bit of thick foil in a MSR box costs £15.

There must be a cheaper alternative?

one from ebay

Yes there is: foil box that disposable BBQ comes in or three layers of kitchen foil or an adapted takeaway box.

Not exactly difficult to work out though is it?

I wondered if folding enough tin foil might work.

I wish I was clever enough to know without trying it 🙄

That’s more like it TT.

I like!

It would help if you were clever enough to use the search function on the forum 🙄

alu foil wrapped a few times round a couple of spare tent pegs?

I generally just use a bit of camping stuff that I’m not using – fold up frisbee, bag, rock, etc…

Yeh this crops up all the time Mattie H.

You sound like a really fun guy 🙄
