This is a size M Tocotien Belt, a navy blue pelvic belt. I used it for about six months, from the fifth month of pregnancy until after giving birth. I started using it early, as I heard it could prevent problems like breech presentation. I gained about 10 kg from 156 cm and 52 kg, but this size still fit. - Brand: Tocotien Belt - Size: M - Type: Pelvic belt - Color: Navy Thank you for looking.
