M∞CARD sold only via the band's official webshop. It features a digital download of the song Journey (single edit) + accompanying lyric sheet. (The single edit differs only in that it lacks the later version's extended intro.)

When announced, the download was said to also include a lyric MV for the song, but this was ultimately scrapped and released on YouTube instead.

The packaging is somewhat elaborate. The card features full-color artwork and is paired with a translucent A4-sized “design sheet” featuring the band's key artwork. Both items are included in an envelope which is wrapped in twine. Each copy features random 1 envelope variant of 4 possible: one with light, smooth weathering around the edges; one with rough, heavy weathering; one with faux water damage; and another with map-like markings.
