LL JP 4 I find pads with synthetic lining to be irritating on my skin (ie. Always brand), so my gynecologist said to use pads with a 100% cotton lining. I used to use Seventh Generation pads in the USA, but can't find that here. If you have sensitive skin and need pads that have a cotton top lining, this is a decent brand. I have a moderate flow, and this is pretty absorbent, and I've had no issues with leaks during the day or night. This pad also doesn't irritate my sensitive skin. It's not my favorite brand, but it's the best brand that I've found in Japan that has a cotton lining, wasn't bulky, and no fragrance.
