This is a Ka’oir waist trainer. I bought from the company in June. Picture of receipt for $101 is included. I have wore this 3-5 days a week, 6 hours a day for 6 months and have lost 40 pounds. It is too large for me now and I purchased a S/M from a lady here on Poshmark. My waist is so much smaller now too. It really works.
