Haven't seen that kind. I have the single cup ones. Have made cupcakes in them in the microwave when my oven was broken. Cupcake liner, fill halfway with batter, 2 - 2 1/2 minutes. Cupcakes!
Some egg cartons, apple containers are just the right size to store christmas ornaments.
I use them to keep flies and such out of my drinks. They are a perfect fit for pop fans.
if you have kids who like to craft they are good for a small amount of paint at a time or water for washing paint brushes while they are working.
also for a craft kids could paint them and put a battery votive, tealight in them for gifts for Christmas. or use them as "pots" for a fake mini tree that could be decorated for Christmas as gifts or fake flowers for spring or Easter.
