They fit together nicely, and the bearings are smooth and quiet.
This was a good set. I’ve bought fidget spinner hardware more than once, and tried out several different options. This one by far is the best as they are the right size they stay together. I have bought a few in the past that were either too hard to take apart or fell apart often these seem to be holding up and the bearings are quiet and they work well together meaning they don’t have a bunch of different sizes That you have to try to fit together like some of the other ones that I bought so these are great. The bearings were a good size. They are smaller than some fidget spinner hardware, but they are a lot quieter and a lot smoother.

Perfect!
Nice mold. Was a little smaller than I expected but the size is great for ones with the smaller hands. I have really enjoyed gifting these out to my students and kids at church!

I wasn't sure about this at first but my son keep pestering me to try this so we did. They actually work wonderful. Nice design and parts fit together perfectly. It really a good price to have some fun making memories with your kids.

High quality bearings - but a little too large for the mold
I’ve ordered these spinner bearings several times because I make a lot of fidget spinners (give them away to kids at craft fairs). They work great but I’m giving them 4 stars because they are slightly larger than the actual hole in the spinner itself. I don’t know if it’s the resin mold that has a smaller hole or if these bearings are slightly larger than they need to be. I still order them - just learned to sand out the hole to make it larger (to fit the bearing). They are good quality and I’ve never had any break (and the kids love the colorful fidget spinners)!

good bearings
smaller than the regular figit spinner bearings which makes them better for hobbies and crafts and toys etc. when theyre clean and dry they spin longer!
