Hi; Again I thank you for inquiry to manufacturer of my new favorite joint medicine. I will continue to order as 50 gram glass bottles and am happy to have such good ointment. It is again better than prescription drug store medications and natural too. Who could ask for more? You deserve top grades in customer satisfaction and 5 star feedbacks X 2 feedbacks. Please let me know if I could help you with e-bay feedbacks further, Your happy customer, Yuri
