This is a refill pack (600ml) for Pomerro Family from Babubabu Midwifery Clinic. This is a set of 2 bags. Although unused, it has been some time since purchase. They were purchased at the Babubabu Store in January 2024 and March 2024, respectively. If unopened, the expiration date is approximately 3 years, so there shouldn't be any problems, but please purchase only if you understand this.
