Spell component pouch

A spell component pouch, sometimes just called component pouch, was a small belt pouch in which spellcasters kept their commonly used material components and spell focuses for easy access.

"The only difference between a magic-user’s pockets and those of a small boy’s is that there is less week-old candy in the mage’s pockets."
