Interlabial pads are like a cross between a panty liner and a tampon. They have a similar absorbency to disposable liners, but are worn differently.
The petal pad (pictured front right) is a small, petal shaped, pad that is worn tucked between the labia (along their length).
To wear them you simply fold the pad in half, or roll it into a tube, seperate your labia, place the pad between them, then let them hold the pad in place.
They are an excellent back up for cup users on heavy days or while getting the hang of cups, or as extra absorbancy without the bulk of a super pad.
They will absorb up tp 5ml of fluid, so are similar to a mini tampon. They have no waterproof backing, and will leak when full, so be aware that these are only very light absorbency - more like a liner than a pad.
Because of their position, they can help reduce 'channelling' (blood running up your butt crack and leaking out) on heavy days and at night - use them in conjunction with a pad.
These are an external product, so cannot be worn while swimming, but you can wear them in the shower if you wish (don't forget to clean down there though). You also need to remember to remove them before you pee (and don't drop them in the loo!)
Because of their low absorbancy, and because they are worn close so can be drying, you need to change these often.
Petal pads are made from 100% cotton - 1 side is flanellette the other is smooth quilting cotton. The quilting cotton helps limit the 'dry' feeling.
I suggest a double pocket wet bag for storing clean and used labia pads while you're aout and about.
