A bag for use in sorting items is provided. The bag includes a body that at least partially defines an upper compartment and a top opening to allow access to the upper compartment. A lower compartment is at least partially defined by the body. Both the upper and lower compartments are configured for holding items therein. The body defines a selectively closable lower compartment opening to allow access to the lower compartment. A partition is disposed between the upper and lower compartments. The partition defines a partition aperture to allow the transfer of items from the upper compartment to the lower compartment based on the size and shape of the items to sort the items between the upper and lower compartments.
