General term for any item or object that holds other items.

Pointers for opening (objects):

in range to open out of range

Types of containers

Bags

items that players can equip, that can contain other items at will.

Lootable objects

These objects appear in the world and can be looted. Once they are empty, they disappear.

• chest objects that can be found around the world and looted. Some may be locked. These include various footlockers, baskets, and so on.
• Ore veins and Herb objects, which require some level of Mining or Herbalism skill (respectively) in order to open.

Lootable items

These items are gained in various ways. As with lootable objects, once they are empty, they disappear.

• Lockboxes that are acquired as loot, and Junkboxes that are gained by pickpocketing. These items are always locked.
• Reward bags, such as the Satchel of Helpful Goods,  [Sack of Frosty Treasures], and the  [Keg-Shaped Treasure Chest].
• Quests sometimes use containers when there are multiple quest items associated with the quest.

Single purpose containers

These objects contain some amount of a single item. While the pointer for opening these containers is the same as that for other containers (eg chests), you are not presented with a list of items that you can choose to get; you simply get one of the item the object has.

• The water tub objects that appear on the ground during the Hallow's End event, which are looted for water to put out fires.
• The Brewfest Keg that appears when the  [Brewfest Pony Keg] item is used, which are looted for a sample of Brewfest brew.
• "Group Consumable items" such as the  [Big Berry Pie] and the  [Lovely Cake]. These items have a limited number of uses before they are exhausted and disappear. Lightwells and the mage table use the same mechanic.

Notional containers

These are things that would be considered a container in the real world, but their contents are not represented separately from the item.

• The  [Water Bucket] item that appears in your inventory when you loot the water tub. It holds water alright, but when you use the bucket, the bucket disappears from inventory.
• The [Blue Brewfest Stein] and the [Yellow Brewfest Stein] items hold beer. When you drink (use) the stein, it transforms from a 'full of (beer type)' stein to an 'empty' stein.
• Some letters you can read, some you can't.
• Similarly, many quest items that are containers (like the  [Dark Iron Fanny Pack]) are only considered in the context of the quest, and thus cannot be opened and examined.
