I won't choose. Put this strategy away.
Look at the thickness
There is no doubt that the thinner the better! Light and breathable, it won't be uncomfortable to stick it inside underwear.
Excessive thick breast pad makes breathing slow, uncomfortable and sultry.
Comfort level
Because it is in direct contact with the skin, the surface layer should be soft and skin-friendly, otherwise it will be uncomfortable to rub it for a long time.
Back adhesion
Non-sticky ones are easy to shift, easy to fall off when rubbed for a long time, and good ones are firm and difficult to shift, so they are also safe to use.
Absorption speed
It is not easy to reverse osmosis if you choose to absorb quickly. Oh, it's dry and doesn't lump.
Slow absorption and easy to get on underwear.
