These pads aren't the most absorbent out there and I find them rather large so they show above my bra. They are also quite rough, so aren't that comfortable and can rustle when moved so aren't that discreet.
However, they are individually wrapped so I found them really good for popping in my bag when I was travelling.
"Slim but too big"
I am not a huge fan of these breast pads. They are nice and slim but to compensate for this they are enormous and sometimes peek out of the top of my bra. They also come in individual wrappers which I think is a massive waste of packaging, and means that they come folded in half. When unfolded they retain a crease down the middle which shows through my top.
