Ok, I finally finished this WPC file. It can be used for money, gift cards, suggestions, notes, etc (If I made the hole bigger I could use it to store those plastic storage bags).
I used chipboard for most of this project. I added marbles to the top and bottom of the container.
If you want this file, you'll have to add your own sticks (and finials if you like). There is also a hole in the bottom with a flap and velcro for easy opening and closing.
One suggestion is to only adhere the sticks to the bottom inside because you'll need some flexibility when adding the middle box cover and the top cover.
If you want the file, I can quote a price for you.
