The price was good, they snap together easily, and spin great! ### ⭐⭐⭐⭐⭐ They fit together nicely, and the bearings are smooth and quiet. *by on Reviewed in the United States August 7, 2025* 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. ### ⭐⭐⭐⭐⭐ Decent quality and affordable for 3D print projects *by on Reviewed in the United States July 7, 2026* Bought these for some 3D print projects, quality seems decent, price was decent ## Frequently Bought Together - 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 - NiArt Fidget Finger Spinner DIY Epoxy Resin Casting Silicone Mold Kit 5 Molds with 10 Bearings Set, Stress Reliever Hand Fidget Toy Gift for Kids and Adults Art Crafts Home Decorations Jewelry (Set A) --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/508511701-niart-fidget-spinner-bearings-with-caps-24-pack-chrome-steel](https://www.desertcart.tn/products/508511701-niart-fidget-spinner-bearings-with-caps-24-pack-chrome-steel) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-16*
