Japanese hard lures.

Japanese hard lures, bass lures in particular, are some of the most innovative tackle in the world. This page tracks live Rakuten prices on cranks, jerkbaits, topwaters, swimbaits, and metal jigs from the brands JDM bass anglers actually fish: Megabass, Jackall, OSP, Imakatsu, Deps, Lucky Craft, Tiemco, Gan Craft.

Lures are the best per-item shipping value in JDM tackle, a single Zenmarket parcel can carry 20+ lures for around a dollar each. Stack a consolidated order over a few weeks before shipping; the math is dramatically better than buying one lure at a time.
