I really like how comfortable these feel - you don't want to feel like you have a ream of paper in your underwear hahaha. Honestly, when using these I barely feel them at all which is something I really like.
I haven't had issues with them slipping or leaking and I find they're a little more discreet due to the size. Because of this you can fit a few of them in your handbag without worrying it will look bulky.
The only reason I am not giving them a 5 star review is because there are cheaper alternatives out there that are just as comfortable and functional.
This invisible range is my go-to one. I love how it truly is 'invisible' - no awkward lines showing through, and they are the comfiest I've ever used -- it's almost (almost) possible to forget if you're wearing one of these, as they're so thin but super absorbent. I've never had a leakage problem with these. Only con, as others have mentioned, is that Libra is a bit more expensive than some brands - but I think it's worth it in this particular case!
