"Pigeon Mother's Milk Realization SS Size Set of 2" is a very convenient baby bottle for babies. Especially as the name "Mother's Milk Realization" suggests, it uses a nipple that reproduces the feel of breast milk, making it easy for babies to drink. The SS size is usually the perfect size for babies aged 0-3 months, with a very small capacity (usually around 120ml), making it perfect for initial feeding. The set of 2 is convenient, isn't it? Even if the baby uses the bottle more often, you can replace it immediately, which is reassuring from a hygiene perspective. I purchased it but have stored it without using it. When shipping, I will include the box and will indent the tip of the nipple. The following is the product description.
