The kits included the vinyl, zipper, heavy interfacing, and the bias binding. I provided the fabrics (there are two of them, the one that shows through the vinyl and the one in the back).
Along with the supplies came a link to a video showing how to put the case together. The video is about 10 minutes in length and absolutely excellent. I think cutting out the pieces almost took longer than the sewing which didn't take much longer than the video.
I can highly recommend this pattern (it's possible to buy just the pattern, without the supplies), the notions case was fun to sew (lots more fun than what I had been sewing before) and I might just make more.
