My BIS lists 3 Shadowlands crafted items when you can only equip 1.

It was my understanding that only the 262 items are unique equipped, but not the 233 items. If that is not the case, I can change it.

I got and equipped the 262 vest and could not equip the 230 rings

The 262 and 230 items share a unique constraint. The 233 items do not have the unique constraint (Mark IV), I believe.

I bought a 233 ring and was able to equip it, interesting. Thanks for the responses.
