The pure:est washing sponge is designed to be extra gentle with your car by having a waffled surface. Dirt particles will be embedded in the deeper groves and not directly touch the paint, which would otherwise create swirl marks and scratches.
Always make sure that the sponge is soaked to reduce friction. This product is sold in a set of 2 sponges and comes wrapped in plastic to avoid getting dirty in transit.
Made in Sweden with love.
