Super Mario: Mario & Luigi Cap Clear Transparent Pouch (Nintendo, Ichiban Kuji, Import, 2020)

Man, Japan just have it all; including a pouch that is also a hat! 
Put it up to your forehead, and pretend it's a hat! Ha ha! That is so cool and funny! 

Or, you could just use it for it's intended purpose, which is a little pouch for your medicine, make-up or toiletries. 

This product was apparently an exclusive prize, from a brand known as "Ichiban Kuji" - a Japan-only lottery, with exclusive prizes from various manafacturers. In other words, this a thing, you could only get if you won said lottery!
It was never available at retail. 

Condition: Great! New and unopened.
