Disinfectant for baby bottles, 60 packets, easy to use. - Brand: pigeon - Contents: 60 packets - Purpose: Baby bottle disinfection - Ingredients: Chlorhexidine gluconate (75mg) Thank you for viewing. I bought this but didn't use it because I was using microwave sterilization. I purchased it in 2022. According to the official website, the quality doesn't change for 3 years after purchase, but please refrain from buying if you are concerned. I haven't opened the box yet, but I will open it when I ship it and send the contents and the folded box. I've set the shipping time to 4-7 days, but I will ship it as soon as possible.
