If that certain someone isn't a plushie fan or can't carry their favorite stuffie around with them, the Poke Ball Classics collection is a consideration. It's a range of professional attire and accessories for adults (or those who have to pretend to be adults during the day).
Though the wallet is shown above, the line contains a number of choices.
It's a great reminder of the child at heart, that the things we love don't have to fall away just because time passes and we grow up. And they look cool, which is always a bonus.
