VERY RARE UNRELEASED Prototype NINTENDO DS Carrying Case

VERY RARE UNRELEASED Original NINTENDO DS Carrying Case Prototype never released to the public You Are Nintendo.
Was an unreleased Prototype design for the Original Nintendo DS Carrying case.
My assumption was that you would go to a store and Nintendo would have a kiosk where you could customize and design a carrying case for the Original DS with a custom background design as well as your Nintendo Mii from your personal Wii and a phrase that you could write.
Which is why you see a wii menu design on the case
With Wii Mii character and the phrase "You Are Nintendo" "One Focused Organization"
Unfortunately this case was never put into production
The Mii on this prototype is mostly likely random or even possible a at the time employee from Nintendo.
Since this ds case was never turned into a full product and just cancel/ Never put in production.
There are very very few.
This is a great piece of Nintendo History and a example of a Nintendo product that could easily be lost to time.
