Chest

The chest can be built for 4 boards and allows you to store 6 stacks of items (32 items each). It can be placed down in any viable place on the ground shown highlighted in white. Multiple chests can be built.

You can simply drag items to the chest and drop in order to store them, or open it and drag-n-drop to the slot you wish to store it in.

While you can safely drop items on the ground and retrieve them later, some bunnies, spiders etc. might come by and eat the dropped food, so it's better to store the food in a chest.
