Magic Box/ Exploding Box

It was recently a friends 40th Birthday and I wanted to make her something special. She loves Butterflies and trying to think of something Butterfly themed to make was quite difficult. But I came up with this:

 Close up of the inside of the box.

 The closed Box with the lid.
I added "40" Gold peel offs to the sides, but didnt get chance to photograph it before I needed to give it

My Friend was thrilled with the Box and said she will keep it displayed all the time.
Unfortunately I cannot claim the design of the box as my own. I found a tutorial by a Fab lady on www.magic-boxes.com
