I recently came across some Sneak Preview Jango Fett figures at Walmart and took a look at the back of the jet packs to see which ones had writing on them and which ones did not. Here was the results.
5 with writing on jetpack.
4 with no writing on the jetpack.
Now I thought that the figures with no writing on the Jetpacks would be a harder figure to find, but they seem about equal to the ones that have writing on them.
I am just curious if this is widespread or just luck that these 3 cases had almost equal amounts of both, so if you want post which ones you found and then maybe we can get an idea.
