The Mana Pouch would be a bag which the player can carry in their inventory, upon right clicking it would bring up an inventory where you can store only Mana Potions. The Mana Pouch's inventory size would be the same as the inventory. The reason you'd only be able to put Mana Potions inside is to make it less overpowered, if it wasn't like that you'd be able to store anything inside which is a bit OP. Anyway, if you have a Mana Flower and a Mana Pouch which has some Mana Potions inside, the Mana Flower will instantly consume the Mana Potions from the Mana Pouch when needed, refilling Mana as if the potions were in the inventory.
