I got this little guy today, and I was excited for how adorable it looks in the photo!
The DIY instructions are online, not in the package. Even with being very precise and using an exacto knive for clean edges, the wallet did not turn out picture-perfect. It is easy, but it looks cheap, and it will not hold much. The edges do not seal all of the way, and if you are trying to hold on to something important, it might just slip out.
I would not recommend. Super cute in theory, not in real-life.
