Equip the herb pouch?

i’m an Elemental Shaman, L 37, herbalism/alchemy. I have picked up a herb pouch, but can’t figure out how to equip it. It won’d go into my bags chain; I tried to equip it on my character (C) but it tells me that it won’t go into any of my slot s. So what do I do with it? I have started picking up herbs and need the storage space

It’s one thing to confuse “legacy” with “classic” or “warcraft 2” with “world of warcraft”, but seriously… read the forum’s name… smh.
