This box trades at $721 — right at its 1-year high. It's in a steady climb: up 56.0% over 90 days and still rising this week. That puts it in the upper part of its tracked range. It typically swings about ±6.3% in a month — jumpy for a One Piece box, so single-digit dips here are mostly noise. Worst tracked stretch: a 10% drawdown from peak.
eBay supply is tightening: active listings are down 11% over the last 60 days (~33 live now). The set's cards are worth about $33,195 — 46.0× the box price, vs a typical 12.8× for One Piece. That rich multiple adds +1 to the score. Across One Piece boxes the median 30-day move is +1.9% (89% of boxes up), and this one is running 19.6 points ahead of that pace. Beating its own market adds +1 — the move is this box's, not the tide's.
Supply is tightening, but the box sits within 5% of its 1-year high — little room left to run, so it's held at WATCH. A pullback below roughly $685 — or a decisive break to new highs — reopens the buy case.
