From True Linen Organic SPA Collection.

Made from natural linen flax and cotton mix base. Great for all your child's bathing needs. It has a convenient hand loop to secure the hand grip.
The most organic and natural way to wash your baby or a child.
The pad is very soft, perfect to wash little bodies yet strong enough for those exfoliating needs.

They absorb moisture very well, do not collect static charges and are hypoallergenic.

As this product is made of natural fibers, separate wash is recommended for the first time.
 
Note: can also be used as a cosmetic sponge.
