Ball bearings are really swollen but this is 2021 and they are just B/B motor quality as some have written. "BBs are round steel balls" of any size, and that's true. The can pictured for sale was a worthy (decorative) addition to my work and play BB containment system (rocket ballast). A previous comment from a customer referred to a "good bank" and that's what solidified the deal for me. Without a collector's tin (like the beautiful Chock Full O'Nuts coffee tin) it's just a few steel balls from the hardware store and that promise is broken. Slightly deceptive seller performance, 4/5 stars.
