When magicians carry out precise ceremonies and spells, they often use specialized tools which correspond to the symbols and requirements for the spell in question, allowing Magic to be executed more efficiently and conveniently. An example of this would be using a spear when using Magic based on a story involving a legendary spear - the spear is not absolutely necessary, and certain items with the same shape and function can be used in its place (such as an umbrella), but details being closer to that of the intended item decrease the odds of the spell failing and makes it more effective.
Spiritual items are mostly nothing more than tools, with a few exceptions. When a magician holds a spiritual item, it becomes a part of their body and part of the magic power flowing through their blood vessel will circulate through it, enabling them to function. This power can also be provided remotely and for some items, magic power will continue to circulate for a little while after the magician lets go of it.
In the past, destruction of a spiritual item would sever the circulation of magic power and damage the magician. Nowadays, safety devices are incorporated into them to prevent this.
