This box trades at $381 — right at its 1-year high. Price has been broadly stable across the last quarter. That puts it in the upper part of its tracked range. It typically swings about ±0.7% in a month — calm by One Piece box standards, so moves that size are worth noticing.
eBay supply is tightening: active listings are down 17% over the last 60 days (~77 live now). The set's cards are worth about $4,364 — 11.5× the box price, vs a typical 17.1× for One Piece. That thin multiple trims 1 point off the score. Across One Piece boxes the median 30-day move is -0.0% (45% of boxes up), and this one is running 0.6 points behind that pace.
Tightening supply with a price that's holding is the classic setup — rated Buy. It's also pushing into new highs rather than stalling at them: supply is tightening while the price keeps making ground, and the last week hasn't turned down. A squeeze that's still being paid up for is the strongest version of this setup, so being near the high counts for it here, not against it. What would end it: supply refilling (the 60-day drop easing back under 10%), or the 30-day price slipping more than 2%.
