This is a one piece therapeutic magnetic waist wrap. It has 16 large 800 gauss magnets in the widest center part of the wrap for a total of 12,800 gauss. It is very easy to put on and take off with the velcro type wrap construction and will be good for waists up to about 40 inches in the medium size before stretching,and includes 8 inches of velcro on one end. It is about 5 1/4 inches at the widest point. Each of the attached 2 end straps are about 12 inches long and about 2 inches wide. It is only about 1/3 inch at the thickest point in the center and about 1/8 inch thick at the ends. We also have this in a larger 50 inch wrap for larger waists. If you want the larger size wrap, please choose the 50″ belt. You should not use magnets if you have an electronic implanted medical device, or if you are pregnant, and should consult a doctor before use. We make no claims for cure, treatment or mitigation of any physical condition. Thank you.
