NiArt Fidget Spinner Toy DIY Bearing with Caps Set 22-Pack, MR137 0.5" Single-Sealed Chrome Steel Bearing Balls Replacement High Speed 13mmx7mmx4mm Epoxy Resin Casting Craft Skateboard Stress Reliever

I am absolutely in love with this mold and kit. My kids are adhd children and love fidget spinners. They are expensive to buy so making them and customizing them to fit them uniquely was well worth my purchase. I have made several of them and everyone has loved them. They spin better then store bought and they hold up well even with the younger kiddos that are rough on toys. Easy to make and assemble.

I needed extra bearing caps for all the fidget spinners I have been making. These have come in so handy.

The media could not be loaded.  AWESOME order, I found missing bearing so ya'll Did awesome job!!!!!!

I do a LOT of epoxy projects and this is by far my favorite so far simply because the quality of the molds and the gears are incredible!

The quality is good. I feel like they could have been a little better quality, but I’m not going to knock it for the price. The bearings do what I need them to do and I haven’t had an issue so far.

They are great except that they break very easily

I got these to put into 3D printed fidget spinners and they are incredibly smooth, I haven't run across bearings like these before.
