This is a combined sale of Nekton S, BIO, and cuttlebone powder K-84 calcium supplement. All items are new and unopened. I am selling them because I no longer need them. Nekton S has an expiration date of 2027.9.15, Nekton BIO has an expiration date of 2027.7.29, and the cuttlebone powder expires in 2027.9. If the photos are difficult to see, I will add more. Both supplements come with a 5-piece moisture protection set.
