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.
Non-Stealth Sponges are formed with traditional angles and do not feature our proprietary “flared” angles to offer significantly reduced artifacts during viewing. Non-stealth (or non-flared) sides may show artifacts when imaging, specifically when coating is applied.
