Spy Kit for a 6yr old girl

[MrsSnaplegs]

DD has asked the big man in red for a "spy kit" -when questioned as to what this is so Mummy can help him find it this is something from her imagination not something that can be purchased

It consists of:
An eye thing that shoots lasers
An ID card for spies
magic drinks that make you invisible
invisible paint to make you invisible
a special outfit with a hat that you pull over your face but it has holes in it
a notebook and pen

So the plan so far is:
night Vision goggles and a listening device I have found in Argos
Grandma is going to sort out a balaclava (knit/crochet/purchase)
a silver sports drinks bottle from a camping shop
an empty bottle and paintbrush labelled as invisible paint
black combat trousers and a black polo neck top plus or minus a jacket
a moleskin type notebook and "posh" pen
all secured in a small briefcase

does anyone have any idea where I can find a small cheap briefcase?
does anyone have any better ideas than above to make this work for an excited little girl

Surely an invisible ink pen?

A combination lock money box or perhaps a cash tin for keeping spy things in.

What about a black messenger style bag? And every good spy needs a head torch

Brilliant idea, btw! Good on DD

Fab thank you great ideas - keep em comin

sounds excellent!

how about a spy handbook
and glasses so you can see behind you these ones have delivery on top, I have seen them elsewhere and in shops

For a briefcase, you could have a look on ebay - 'suitcase' might throw up better search results than briefcase
like this one (probably over budget, but cute)

or try a cheapy home store for cardboard storage boxes shaped like briefcases. I have Store 21 nearby which has loads. Or IKEA is bound to have something?

Theres a personalised secret agent notebook on funkypigeon.com, I got my nephew one!

Here

Cardboard with newspaper glued on to either side and holes cut in for eyes to peek out - laminated if pos.

That spy guideook that iheartdusty linked to - both DH and I were obsessed with this (and the detective one) when we were little. The first review that's coming up on Amazon at the moment is very amusing - while I was laughing he came over to see, and has ordered it for old times's sake, despite DD being but one year old... It's maybe for someone just a little older than 6 though?

In fact, when it arrives, I'll probably be full of ideas...

Brilliant all of you thank you so much! Now a trenchcoat for a tall 6 yr old

How could we forget a magnifying glass?!

Ah yes she has a big magnifying glass and compass already

She did ask for rope for climbin up but I said I didn't think Santa did rope - not safe at 6

Also, these are an absolute must.
