This is a prefolded muslin nappy (flat) that comes in a pack of four. They are useful cloths to have around for all sorts, never mind being nappies! These nappies are one size so will fit from approximately birth to potty - they might seem bulky on a tiny newborn but won't take long to feel more proportionate.
A Nappi Nippa might help you to achieve some folds but a simple pad fold will also suffice.
Here is the info from Bambino Mio:
Onesize* nappy for use from birth to potty training.
Multi layers of cotton provide super absorbency, keeping your baby dry.
Beautifully soft, natural and breathable against baby's skin.
No bulk around hips and under clothes.
Fold in a variety of ways to adjust absorbency and simply tuck into miosoft nappy cover.
Easy to wash and extremely quick drying time.
4 nappies per pack.
Made from 100% cotton.
*True for most, but due to the wide range of babies' shapes and sizes, this cannot be guaranteed.
Machine wash warm up to 60°C. Do not use chlorine bleach. Do not use fabric softener. Do not iron. Do not dry clean. May be tumble dried warm. To get the best out of your nappies, we recommend washing them at 40°C with non-biological washing detergent and one scoop of miofresh natural laundry cleanser (15mL). Air dry your nappies away from direct heat. Washing at higher temperatures and frequent tumble drying can result in premature deterioration of your nappies
