Sacks

Sacks allow the player to store a certain amount of Collection items while held in the inventory or a Sack of Sacks with the exception of the Candy Sack, Rune Sack, slayer sack, and Dungeon Sack. Players can collect the items stored in the sack by opening it and then clicking the item that they want to collect, somewhat similar to that of a bazaar buy order. enchanted sacks function the same as regular sacks; they just store the enchanted form. Enchanted sacks only have the large tier, and work along the Super Compactor 3000 and Personal Compactor 4000 and all of its tiers.

All items within the sack can also be quickly sold using the quick sell option at the Bazaar, even if the sack is stored in a chest on the private island.

Having multiple Sacks stacks the quantity of items, and the sacks cannot be traded or put on the AH, even through Backpacks.

Note: Even though there are 17 sacks in the game, you can only hold 16 at a time. Even if your Sack of Sacks is maxed, it is unknown if this is intentional.

Tiers
There are three tiers/sizes of sacks in total. Each tier allows the player to store more items than the tier before it. Holding multiple sacks of the same type adds their capacities.
