Summary
This is an official Apple Music pre-order benefit postcard featuring the full fromis_9 unit from the 2024 single album Supersonic — the Miami-bass summer anthem that peaked at #2 on the Circle Digital Chart with four music-show wins. Group shots from a career-peak era are the hardest POBs to find complete.

Visual & Specifications
Full-group photo in the single's sporty summer Y2K concept styling, printed in postcard format (larger than a standard 55 x 85 mm photocard) with a smooth matte-gloss finish — made for display as much as collecting.

Collectibility
Unit postcards were only available through Apple Music pre-orders, so far fewer exist than member PCs — group-completionists and ot8-era collectors compete for every copy. When buying, confirm sharp group-print detail and clean edges, and store flat in a postcard sleeve to prevent corner wear.
