While many subscription services deliver boxes of treats directly to their customers' doors, none of them do it quite like this. Unbound offers a discretely shipped, curated quarterly collection of the latest high-end erotic toys and accessories, each selected with a playful theme or experience in mind. These themes include “Femme Fatale,” “Soirée,” or “G,” a box focused on the g spot. The contents are also enhanced with sexual-wellness resources and suggestions, such as playlists for getting in the mood and access to an educational online magazine.
