These displays are Fluxx branded with the logo and generic Fluxx imagery, but not branded to any specific Fluxx game, so you can mix and match six Fluxx card games in one display (or 3 of Fluxx: The Board Game).
The six open slots are perfect for mixing my Fluxx games instead of having five separate boxes sliding around. Cards sit snug and nothing falls out when I tilt it. Exactly what I needed for my shelf.
The open slots let me finally shelve six different card games side by side instead of stacking boxes, and the generic logo means nothing clashes when I swap them around. Took me a minute to figure out the tab orientation, but once it clicked the whole shelf looks intentional.
Finally a way to keep my collection from turning into loose decks all over the shelf. The display holds six different card games at once, and since the branding is generic instead of tied to one title, I can rotate whatever I'm into that month. Cards slide out easy without the whole stack toppling.
