Unused, but the silver seal on the toothpaste has been removed, so I'm offering it at a lower price (a nurse at the animal hospital opened it for me to smell when I bought it, but I haven't used it). The sample's expiration date is November 2025. The toothpaste's expiration date is January 2027 (the "01 27" on the far right of the third photo indicates the expiration date. I bought it at the hospital last fall after my cat's dental surgery, and the number on the left is not the expiration date). I'm sorry, but I can't lower the price any further due to packaging and shipping costs. I can also ship it with the recipient paying the shipping costs. I'm truly sorry (＞人＜;)
