8 disk mounting washers and 8 disk mounting screws.
All models except minishred
Pack received quickly in a box while it could have been shipped in a small letter (Think green 😜).
I bought the set for 390 Boss bindings dated 2014 - time flies. Disk hardware are not totally similar, disc or washer are smaller and head of screws is not flat as the original ones but they fit well and should be okay in the end.
Next step is waiting for Summer session or next Winter 🤟
