Bulu box. the first and only vitamin and supplement sample box, send me this box to review. Bulu Box includes a well-rounded sampling of vitamins and supplements that help in all areas of health. Each box contains 4 to 5 premium samples plus lifestyle extras from time to time. There is a regular Bulu box and a weight loss Bulu Box. The Bulu Weight Loss Box was designed with the specific goal of weight loss in mind. Each box contains 4 to 5 premium weight loss items such as vitamin and supplement samples, fitness gear and healthy eating tools. I really enjoy this box, because I can try supplements and vitamins, before buying an expensive jar of something I might hate.
