I used this for about a month after giving birth. I only used the pelvic belt about 3 times. Retail price: ¥6,710 (including tax) [Product Description] This is a special online shop exclusive set of the Inujirushi 3-Step Reform Step 1, "Postpartum Nipper" and "Postpartum Pelvic Belt," which can be started immediately after childbirth. It is said that a mother's body is suitable for body reform from postpartum to about 1 year after, due to changes in hormone balance and pelvic condition. Let's reform to a more beautiful body shape than before pregnancy with the correct approach. [Good Design Award Winner] The wide nipper firmly supports the abdomen and waist. It is made of soft material but tightens firmly, and can be worn even when sleeping. With Inujirushi's unique front cross structure, it can be easily put on and taken off even while lying down, and is recommended as a childbirth preparation item, making it easy for midwives to put on. [Mothers Selection Award Winner] This pelvic belt is made of soft material and is ideal for pelvic fixation immediately after childbirth. It has the same soft material as the nipper and a front cross structure that tightens firmly. The Velcro allows for subtle size adjustments, so you can use it for a long time from immediately after childbirth. ■Size (cm) <Postpartum Nipper> Postpartum M <Postpartum Pelvic Belt> Postpartum M
