IMS Moth Balls are created with the highest quality ingredients. This means that they last longer and the smell is less overpowering. Even better - they are gentle enough to be used with your most expensive, fashionable clothing so that your closet freshener doesn't have to be replaced as frequently as the latest fashion trend. IMS Moth Balls are safe enough to use with the finest wools, furs and silks. It's a good thing IMS Moth Balls have a scent so soft that it vanishes after airing your favorite items.
