These are new Yubikeys that were left over from a big bulk project purchase. The 5Ci model appears to have some scratches on it as seen in the pictures, but is still 100% new and working. Just from being in a large case of keys for a project. These are all 100% new and unused!
For any questions, feel free to reach out! You are getting a huge deal off MSRP prices! Hurry up before they are all gone fast!
