I know this had been a topic of conversation on here before. But this is something I came up with. These boxes are simply trading card storage boxes. They come in multiple sizes, with multiple dividers. So you can really cram a lot of seed into these boxes. And a lid too for nice and clean storage!
The box in this picture holds all the remaining 2015-2017 seed, plus up to division 6 of the 2018 seed.
