The full story
Everything to know about Kore Baseball
Kore Baseball looks like a regular baseball, with leather-style cover and red stitching, but the inside is a soft cushioned core. The idea is a ball that plays like the real thing for catch and practice without the sting, so younger or nervous players can keep their eyes on it.
Dave Koelliker designed the ball in 2014. The family carries the business on: Susan Koelliker leads it, with sons Charlie and Will working alongside her. Kore also sells bat-and-ball sets, a foam bat, custom-taped bats, a softball and youth camps.
Where Kore Baseball is now
Kore sells direct through its website and lists independent retail stores. An Amazon listing for a Kore soft baseball exists, but its seller has not been verified, so the button here runs an Amazon search rather than pointing at one listing.
Where to buy Kore Baseball
Kore sells direct at korebaseball.com, where on November 4, 2026 a single ball was $9.99, a 4-pack $36.99 and a 12-pack $89.99, with bat-and-ball sets from $32.99. The site also points to independent retail stores, and an Amazon listing for a Kore soft baseball exists, though its seller was not verified. The ball looks and feels like a real baseball but has a soft core, so it suits backyard catch, younger or nervous players and indoor-safe practice. It is not a replacement for a regulation hardball in league games, and a foam-core ball will not fly or carry the same way off a bat.
