Here are 4 sets of ClearCorrect aligners. They have been used, but have been disinfected. Those who want to see how their teeth move may find this helpful. Notes: ① I may not be able to reply immediately due to work, etc. ② I try to ship as soon as possible, but since my return home from work is irregular, it takes 2-3 days to ship. ③ I will prioritize those who purchase at the listed price. ④ There are no smokers or pets in the house. ⑤ I try to describe the condition of the product clearly, but please understand that the appearance in the photos may differ from the actual product. If you have any concerns about the condition of the product, please ask questions until you are satisfied. If you are still concerned, please refrain from purchasing. Most of the products are used items stored at home by amateurs. Please refrain from purchasing if you are looking for perfection or are very sensitive. Please note that we are not responsible for any accidents after shipping.
