If you're waiting for a Project Fi invite, this is what you can look forward to when you sign up.

Google has done some neat packaging for its Nexus devices and accessories (Google Glass was particularly high-end), hardly cutting back on the presentation. Project Fi is no slouch here, and Google sends out a very large box when you sign up for the new carrier to help make sure you have a good first experience with the invite-only service.

The welcome box, which is about the size of a Nexus 9, matches the look of Nexus device boxes with white cardboard and bright primary colors inside. And when you open it up, you're greeted with a great stash of accessories for your Nexus 6. Check 'em out.

The box is divided into three sections with plastic containers holding a set of headphones, a mobile battery pack and a white case for your Nexus 6. Each one is neatly wrapped in plastic with a cheeky saying on the front, and will definitely have you feeling giddy if you're a Google fan.

The headphones are white with blue ear tips (there are three pairs) and a green/white/blue volume rocker along the right wire with a nice "Fi" logo on it. The headphones end with a gigantic 3.5mm headphone jack that has a splitter coming off of it so you can plug in a second set of headphones "for a friend" ... I don't really need to share my music all that often, and with how big the headphone jack is I can guarantee I won't be using the headphones at all. Shame, they're actually quite cool other than that.

The battery pack carries the Google colors and a Project Fi logo on the front, and has a 6000 mAh capacity. It has dual USB outputs — one at 2.1A and another at 1A. The design of the battery is decidedly more practical than the headphones.

The case is a very standard white Case Mate model that's a hard shell with a small rubber bumper that goes on it to give it more grip around the phone. Another "Fi" logo adorns the bottom-left corner of the back, and the button covers on the side are fun blue and green colors.

Even if you don't plan on using Project Fi for long, the limited edition accessories you get are at least a cool consolation prize for signing up and giving it a try. We'll be following up with plenty of impressions of using Project Fi in the coming weeks!
