SOFINA iP Keratin Treatment Base cosmetic lotion Opened, used, one bottle. Thank you for viewing. Purchased in 2025.5 Used for about 5 days, but it didn't suit me, so I'm selling it. Since it's been opened, I want to sell it quickly. The empty box says it comes with samples, but I used them, so they are not included. Thank you. ※The background package is the empty box.
