Thank you for viewing. Nekton S 150g Purchased on Rakuten on November 20, 2025. I am selling this because I am raising my birds on pellets(^^) The product description says it is a set of 5 items, but I have not opened it, so I have not confirmed this. I was once told that an unopened item had an inner component of a different size. I have not confirmed the contents by opening the package, so Thank you for your understanding.
