Bulu box is a monthly subscription box that sends 4-5 vitamins, supplements and other health product samples each month. There is a regular Bulu box and a new weight loss Bulu Box. The weight loss Bulu box sends 4-5 vitamins, supplements, fitness gear and healthy eating tools. I was sent the weight loss Bulu box to review. The website says they send 4-5 items each month, but I received 6 in my box.
