I have a question regarding nipples of Lansinoh.
It looks like to very similar to nipples of Japan's products (DoubleHeart nipples). I wonder if they're same products..(a technical tie-up or same base).
Please answer my question as soon as possible. Thank you.
Imjung, thank you for your inquiry. The NaturalWave Nipple and the double heart nipple are the same peristaltic nipple in design and manufacture from our parent company, Pigeon.
