Arrived two days earlier than estimated. There was a plastic seal around the lid as well as a seal under the lid. The bottle came wrapped in 3 layers of bubblewrap in a bubble mailer. There's also an expiration date of June 2023, so it's well within date. I bought this to help treat a chicken with wry neck so if it doesn't work for me, that's not the fault of the product. I will definitely buy this product again if I need to. Edit: It worked! And the capsules are super easy to break open and add to their water and feed. I love these
