Bags 7 and 8. 7 just finishes the front while Bag 8 adds the antenna and handle. Plus, the "sound brick".
To be fair, I'm a little underwhelmed by the sound brick. It plays 6 pre-recorded clips. To activate, you have to "turn" the on switch and then "scroll" until you hit resistance. It's a little awkward. My phone fits in the back but you do have to remove half the back to get the phone in and out.
Overall, still happy to have it. Thankful for the printed bricks and the overall concept.
