Unveiling of “Now Printing” in JP Albums

How long does it take before they unveil what the album editions look like? Like the cover? And also what the inclusions look like e.g. cards, acrylic stand, etc?

Fuwa's 1st Album is now up for pre-order but I wanna see first the cover of the editions and also the acrylic stand bonus before I order but there's a note that the bonuses are limited so I'm torn if I should order right away or wait first for more pictures/info 😭
