About the Mizuno JPX-825 Pro
The JPX-825 Pro is the Grain Flow Forged model of Mizuno's JPX-825 family, sitting above the cast JPX-825 with a more compact head. The 4- to 7-irons use a milled pocket cavity for a lower, deeper centre of gravity while the 8-iron through gap wedge move to a full cavity design. Lofts are about one degree weaker than the cast JPX-825 — a 33-degree 7-iron against 32 — with a shared 45-degree pitching wedge, and the stock set runs 4-iron through gap wedge. Mizuno unveiled the JPX-825 family in autumn 2012, with US retail in early 2013, so year_introduced records the announcement year. Lofts, lies and lengths listed are the men's standard steel-shaft specification.

Finding a used set
The Mizuno JPX-825 Pro ran from 2012 to 2014 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.
