Nail supplements

My nails felt a bit brittle lately, probably because I haven't been eating well, so I mentioned it to a friend, and they recommended a nail strengthener. I can't believe something like this exists! Haha. I thought vitamins were the only kind of supplements... Anyway, thanks to this, my nails are really getting pampered. It doesn't look super fancy, but it's actually a bit pricey. I haven't used it many times yet, so I'm not sure about its effectiveness, but I plan to keep taking care of them consistently.
