Review on 🔧 Sackorange 20 MR115 2RS 5X11X4mm High-Performance Replacement Precision Bearings by Adam Browning

There are 20 of these, I think I need 5mm ID and they are round. Also, it looks like a metal bag sealed from scratch, one or both sides, with green, red, blue inserts, and I had one that didn't even fit in width, it was about 25% larger (photo). Some of them also seem to be slightly magnetic. They're probably good for DIY projects that don't really require 20 consecutive parts. I wish I had listened to some of the other reviews.
