Where to buy boxes? (pony specific)

[Birdeh]

So, lemme start off by explaining.

Most people have seen my display, ponies on top of boxes with their glitter variants in front of their boxes.

Well the very first funko figure I got was Fluttershy. I was so excited to get her home and put her on my shelf, I didn't have a set way of organizing so I threw the box away.

This wouldn't be a problem if I didn't have her glitter yet, but hers was the first glitter I got too, and the box also went in the trash.

Quite a few of my ponies don't have boxes, but all of them are also missing their glitter counterpart, so I'll be able to get the box then.

Is there anywhere I could find a fluttershy box? :x
