How do you properly create holdable items?

I have a prefab of an item that has a scriptable object attached to it. Inside the SO includes the enum type and other things such as the sprite and the string name. However, is this the right way? Or should we have just the scriptable object that also references the prefab of the item? Or should it be a better method? Because currently what I'm doing is creating a purchasing system where pressing a button spawns the specified item.
