POLA Wrinkle Shot Medical Serum N 20g Remaining amount including container: approximately 22.25g Purchased from a specialty store after pre-ordering a lucky bag from POLA's official website. Authentic product. Please check the last page. Only those who understand that this is a used item are kindly requested to purchase. I believe there is about a week's worth remaining. Please refrain from complaints such as "the amount remaining was small." Will be shipped in simple packaging. Only those who do not mind and understand are kindly requested to purchase.
