Which items can you get only get once per a game?

I want to experience the magic of Alola once more, and embark on another island challenge. So I am restarting my game. Before restarting though, I am gonna send over all of my current competitive, rare, shiny or hidden ability Pokemon over to my friend for safekeeping. I will also give them the rarest held items, so that I will not lose them. Can someone try and tell me which items you can only get once per game? Just tell me the names, I will understand why it should be so. My current list includes:Masterball, gold bottle caps, regular bottle caps, adamant orb, griseous orb, lustrous orb, arceus plates, genesect drives, amulet coin, lucky eggs, soul dew, eviolite, red orb, blue orb, mega stones, prism scale(it’s hard to get), dusk stone, starf berry, PP ups, PP maxes, rare candies,…I can get battle points easily later, not a worry. Mega stones only cuz they are expensive.Thanks in advance!
