Non-Coated sponges are a basic (core), open-cell piece of foam. These sponges do not feature a cleanable surface and are not resistant to fluid absorption.
Stealth sponges are designed with proprietary "flared" angles to offer significantly reduced artifacts during viewing. Flared sides will increase overall size.
