Pack of ten Space Shuttle Waste Collection System (WCS) liners, plus one loose liner. The collection container was attached to the WCS wall. It had a suction hose attached to the bottom. The crew member put a liner in the container at the start of every major visit to the Space Shuttle Commode. The WCS was not designed for anything but human waste (i.e. no tissues or wipes allowed). All tissues, wipes, and gloves were deposited into the liner. At the end of the activity, the liner was removed from the container, draw strings pulled tight, rubber band wrapped around, and placed in the wet trash storage bag in the WCS. All 135 Space Shuttle flights carried a supply of these liners. The consignor notes that this Class I flight item was purchased as NASA surplus.
