Help with male rings

Hi all!! I have been working on getting my man a ring (he told me what he wanted and I went from there), but I’m wanting ideas for something special I could do for him. I know men don’t wear their ring until the wedding, but I wanted to surprise him with something special he could have until then during our engagement. I don’t want to be getting him another ring, but is there anything I could get him that he could have on him/wear during our engagement? Thanks!!
