Some sit around in the travel drawer. You know the drawer with voltage converters, passports, weird money from here or there. One sits in the guest room.
I am still ticked I forgot the United Commemorative last 747 tin box one on the airplane.
The strangest ones were from IcelandAir. Plastic stacking hexagon boxes with items from the Blue Lagoon in them. The lip balm was great for the trip, the boxes came back and now hold screws and things on the workbench. None so far have slippers that fit an American size twelve. I'll have the significant other root out some of the older ones and give them to the mission store. t
