It is true that anyone may remove the NightCap Scrunchie, but they can’t be slick this time around. Someone will eventually notice their bad intentions. Having said that, people should primarily view this product as a good option to covering a drink, which normally includes using one's hand or a napkin. From the looks of it, the only way for the NightCap Scrunchie to provide a sense of safety is to keep the drink nearby.
