Used a few times for a wedding ceremony. I personally think it was effective. It's quite expensive, with a list price of 22,500 yen. The upper part of the nipper has a unique cutting design to prevent pressure around the stomach and is cut to fit well with a bra. The hooks have 3 stages and 13 rows for stability, allowing adjustment to fit your body shape and condition, and also supports diagonal wear. Seven coil bones create a beautiful, defined waistline. The flexible coil bones are used, so there is no tightness, and it fits the body line. The loops that enclose the bones use a soft, skin-friendly material. POINT ・Silk protein power net usage increased by 200%!! ※This silk protein is very comfortable to wear and has a good feel, and is highly functional with heat retention, moisture retention, and moisture absorption/release properties. ・Far-infrared power net usage increased by 110%!! In particular, the area of far-infrared fiber has been dramatically increased (almost the entire surface uses far-infrared bare cotton jersey).
