Brand new, unused, as they were remade mid-treatment. Set of 14. ■ These are custom-made to fit an individual's teeth and are therefore not wearable. ■ Due to personal information, the top portion of the packaging will be cut off before shipping. ■ These may be helpful for those studying orthodontics, those interested in Invisalign, those wanting to understand the progress of their orthodontic treatment, or dental students. Thank you for looking.
