The material used in the Welch Allyn Reusable Polypropylene Specula is lightweight but durable. The SofSpec Specula's elastomer tip provides comfort and durability. The specula may be autoclaved, boiled, or sterilized in solution. They are specially contoured for ultra-pneumatic seal and can be attached easily.
I did receive this piece. It was everything it claimed to be. No complaints.
