These things really work. Wish they were available at CVS! Bought 3 the last time, and I'm going to order some more. If you can't read Japanese, this is how they work: remove the plastic, put in your freezer, and replace when the charcoal has disappeared from the container. It slowly evaporates over time. Should last several months before it needs replacing.
