We shared this photo with Dad and he said "is she getting bigger or are the boxes getting smaller?" so Sarah got out the tape measure and said "it's 6" x 10" x Ginny" because she will definitely go to great lengths for a joke
If she isn't getting smaller, then it's probably not because Ginny is Mickey Mouse, even if it's probable she could in fact be a Scottish Lord. I mean, that's a good Jelly Belly Box, and the context of the contents are even more impressive.
