## Description

NiArt Fidget Spinner Toy DIY Bearing with Caps Set 24-Pack, MR137 0.5" Single-Sealed Chrome Steel Bearing Balls Replacement High Speed 13mmx7mmx4mm Epoxy Resin Casting Craft Skateboard Stress Reliever

Review: 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.
Review: expensive, reliable, fun - I make my own figet spinners out of epoxy resin. These are pleasantly inexpensive, they glide into the center hole, with ease, and precision. I have purchased these in the past and have yet to experience any complications with them. I have rheumatoid arthritis and so it's extremely important for me to have hobbies that don't cause me more pain than already have so not having to struggle with them is fantastic! I then in turn, sell my fidget spinners for an extra income so customers dont complain either. I'd recommend these to anyone, I wish there was an option to buy in bulk from this manufacturer
