I'm selling this because I have some in stock at home and accidentally bought a duplicate. I purchased this item new. The sponges were different colors from the start. I opened the bag, but I haven't used it. I hope you understand. This is a set of two brushes for cleaning baby bottle nipples. - Brand: Pigeon - Quantity: 2 brushes - Type: Nipple brush - Use: For cleaning baby bottles Thank you for looking.
