5.0 out of 5 stars They’re balls!
Reviewed in the United States on August 24, 2023
So, I purchased these and some high powered magnets and, (when they say to be careful, thy mean it, those things will fly together and smash a finger! You cannot move fast enough either! Then, mine smacked into each other, breaking a magnet, so be careful a ) I set up my own dent repair kit to use on a couple of my saxophones! I ended up with 1-1/2”, 1-3/4” and 2” balls. I glued a scrap piece of leather to my 2 high powered magnets (bought here for $20-ish) I also bought these steel rollers for rolling out dents and a dent chasing hammer here, on Amazon, I didn’t spend but maybe 80-100 bucks! And a dent ball magnet kit alone, at the music shop is like $1200-$1500, no joke! They work great, and saves a ton of money, but there is a learning curve, and realize, you may not get the dent removed 100%, but 80-95% isn bad!

5.0 out of 5 stars Big Shiny Balls O Steel!!!! OH MY!!!
Reviewed in the United States on November 6, 2023
I randomly saw these while looking for 11mm Bearings to use as Pachinko balls in for my collection of authentic vintage Pachinko Machines from a Yakuza run Pachinko Parlour in Tokyo. Once I saw these I ended up with a pair of 1” 1.25” 1.5”1.75” 2” 2.5” 3” 4” 5” to display. Man these are really heavy and I keep them displayed with the 2” and 3” in my coffee table. Everyone who come over unfortunately be come absolutely mesmerised by the size of my Shiny Steel Balls, they can’t resist them. It quickly progresses to people touching my steel balls and then nonstop fondling my Steel Balls for hours. They don’t want to put them down. One person actually tried to walk off with them attempting to take them home. I have to watch my steel balls like a hawk. The worse part is people always leaving them smeared with finger prints. I might end up locking them behind ballistic glass for safety! You should get your own pair of big shiny steel balls a pair is better then one!!! Your life will change forever!!! Hands up n Hands down buy your own set ASAP!!! You can’t go wrong with multiple sizes of Big Shiny Steel Balls!!! Do It Now!!

Purchased to be the beefy core of a monkeys fist knot. The weight of this is substantial and I suspect most would go a size smaller.

These were reasonably priced and worked well.

1.0 out of 5 stars Will Rust your paints
Reviewed in the United States on April 8, 2024
Does not claim to be stainless steel however who in the right mind uses anything else for "Paint mixing". Do not use this product to mix anything you don't want to inherit a red hue and micro rust flakes.

Essentially garbage because it pollutes whatever liquid it rests in. Thank you for ruining my paints and varnishes.

4.0 out of 5 stars Great Customer Service
Reviewed in the United States on May 19, 2024
Case was broken, bearings rolling out of the case...Updating rating. Shipper contacted me immediately and is refunding $. I bought these bearings because they were in a case, but the case arrived badly damaged and unusable. I will just buy a different case. The bearings themselves are of quality. Thank you for great customer service. Note, these were shipped in only an envelope type mailer.

Bought these to weigh down filament spools that were below the 50% mark. Does a great job securing the spools so they don't bounce around in my multicolor system!
