Super Mario Galaxy: Luma Phone Charm Dangler Gachapon (Nintendo, 2000s)

Hard to find mini-figure to hang off your phone, but it's also just a cute little collectible. 
These things are almost impossible to find these days, and only growing in popularity!

This one, was used a promotion for Super Mario Galaxy, and it's nearly impossible to find. 

Condition: Good! But we're not sure if part of this is missing - maybe there was a Mario attached to it at one point.
