Amazon カスタマー 4 I really liked how strong and shiny it made my fingernails. But after a week of using, i noticed something when I scooped— at first i thought it was just a portion of powder that got crystalized but when i looked more into it— it looks like a small worm? Idk what it’s called.I was shocked so i dug more into it to check if there’s more— i was relieved when i found nothing more.I still plan to take it and to buy every month as i see good effects from it. :))
