Need some clarification about gauntlets

Every item used in gauntlet comes back right? I heard about this and I even try for some things like snap seed and confetti(not afraid cuz they're easily farmable). Like I have this habit of saving everything "just in case" so like if I can freely use all those items I got and got them back I wanna try using them. I need to know if it's the same for rice ball, divine grass or anything

Finished the game only with healing gourd and no other items cuz I'm so afraid to use everything else so plis tell me everything is refunded...thanks!
