OMYOPY Official Size 12 Softballs - Fastpitch Practice & Tr

The Verdict

If you’ve ever bought a dozen “official size” softballs online only to find they measure closer to 11.5 inches or feel like foam-filled toys, you know the frustration. The OMYOPY 12-inch fastpitch practice softballs sidestep that trap. These are real softballs — full-size, leather-covered, and built to survive the abuse of daily practice.

Here’s what you actually get: a dozen regulation-size 12-inch softballs weighing in at the standard 6.5 ounces each. The covers are genuine leather with raised seams, which matters more than most casual players realize. Raised seams give pitchers something to grip for drop balls and rise balls, and they help infielders read spin off the bat. The cores are cork and rubber composite — dense enough to feel like a game ball off the bat, but not so hard that they’ll rattle your teeth on a cold-weather line drive.

Real-world performance is where these balls earn their keep. I’ve seen reviews from coaches running full team practices with a single dozen lasting an entire season. One Amazon reviewer put it plainly: “Bought these for my daughter’s travel team. We’ve put 30+ hours of hitting and fielding drills on them and they still look almost new.” Another noted, “The seams are actually raised, unlike the ’leather’ balls we got from another brand that were smooth as a cue ball.”

That durability comes from the leather cover being properly stitched, not glued. Cheap balls separate at the seam within a week. These hold together. The tradeoff? New balls have a slick finish that needs breaking in. A few infielders mentioned dropping throws early on because the leather hadn’t softened yet. Budget a couple of practice sessions before game-level confidence with these.

Where they fall short: No certification stamps. These are not NFHS or NCAA approved, so you can’t use them in official games or league play. That’s fine for practice — that’s literally what they’re marketed for — but if you’re coaching a team that needs game-legal balls, look elsewhere. Also, the white leather shows scuffs quickly. They’ll look beat up after a few weeks even though they’re structurally sound. Cosmetic wear, not functional failure.

There’s also the occasional inconsistency complaint. A handful of buyers reported one or two balls in a dozen arriving with slightly flat seams or a tacky residue from manufacturing. Nothing that affected performance, but worth inspecting your shipment on arrival.

Who should buy these: This is a solid pickup for fastpitch coaches stocking up for team practice, parents of players who go through balls weekly in the backyard cage, and high school players who want a ball that feels close to game spec without the game-ball price tag. If you’re a slowpitch player, skip these — you need the 11-inch or 12-inch variants specifically designed for your game’s weight and compression standards.

Frequently asked questions:

Are these balls safe for pitching machines?
Yes, but use the leather-side feeding option if your machine supports it. The raised seams can catch on some two-wheel machines if fed incorrectly. Most buyers report no issues with standard pitching machine use.

How do they compare to $100-per-dozen game balls?
They’re about 30-40% cheaper and slightly less dense on impact. You’ll notice a marginally softer feel off the bat, but for practice repetitions, the difference is negligible.

Will the leather peel after heavy use?
Not if you keep them dry. Leather softballs left in a damp bag will degrade. Store them in a ventilated bucket or mesh bag, and they’ll last a full season of regular use.

The Verdict: Buy them if you need durable, true-to-size practice balls that won’t break the bank and can handle daily team drills. Skip them if you need certified game balls or if you’re a player who’s sensitive to the slightly slick new-ball surface. At 4.6 stars from 229 ratings, the consensus is clear: these are among the better value practice softballs on Amazon right now.

Rating: 4.6/5 — Deducting half a star for the lack of certification and the break-in period on grip, but for practice purposes, these deliver exactly what they promise.
