Sending a parcel with AR

The problem: Recently, I was sending a parcel using a Parcel-Motel-type of service. I really liked the overall experience but came across a pain point where I couldn't figure out what dimensions my parcel is (and I didn't have a tape measure around).

The solution: apply a simple AR mechanic (similar to the iOS Measure) to determine what size is your parcel and recommend a suitable parcel box.
