Formerly known as "Sanyo", it is the No. 1 brand of maternity care kits in Japan, and about two-thirds of mothers choose its full care kits. In terms of belly bands, contrary to Inujirushi Honpo, the products of Birthday Fortune are mainly cotton, with good comfort, large size range, and good applicability, but the design of Velcro is not careful.
 
Although the cotton material is comfortable to the skin, it lacks elasticity and is not easy to carry around during maternal activities, while spandex has good elasticity and is a high-elastic fiber necessary for high-performance clothing in pursuit of movement and convenience. In order to increase the flatness and shrinkage of the product, 2-10% spandex is added to the side waist to ensure comfort while increasing the tension of the product and avoiding curling or moving upward.
 
The Velcro of the Birthday Blessing Belly Belt is divided into one-piece, two-ear and three-eared parts, but it lacks the two-way cross design of the Inujirushi Honpo, the pressure exerted is limited, and the left and right forces are not as uniform as the Inujirushi Honpo. At the same time, its lower width is narrow, and for caesarean section, it is easy to cause uneven force at the abdominal wound, and it is more recommended for women who give birth naturally.
 
Birthday Fu has carried out a special division for smooth delivery, special for caesarean section, and general use for postpartum ready-to-use abdominal belts, but there is no obvious difference, but the special abdominal belt for cesarean section will be slightly larger in size settings, and the prices are between 180-315 yuan, compared with the previous brands, the cost performance is acceptable.
 
The strengthened type has higher requirements for plasticity, and the double Velcro is used to achieve a better fixation effect, and the feeling of abdominal tightening is relatively strong, which is suitable for 1-2 weeks of normal delivery or 1 month after caesarean section. The Chinese market sells original Japanese products, but the size is not as complete as the official website of Japan, and the price is about 400 yuan.
