Zazyg's Spell Component Pouch

This item is a normal belt pouch of unremarkable sort. The famous archmage Zazyg is rumored to be the first crafter of this magic item. When you wear this magic pouch and you are casting a spell you pick from the pouch a desired material spell component of a value up to 100 gp. The component always disappears after you cast the spell. Once used this property three times, you must finish a Long Rest before you can use it again.
