What is Yellow Stuff™?

We’re proud to say that since we introduced Yellow Stuff™ exclusively in 1993, it’s become the leading impression material on the market. Over the years, we’ve continually worked to improve the consistency of the mix, putting Yellow Stuff IV™ on the top shelf of impression materials. Along the way, we’ve received personal endorsements from major manufacturers and other hearing healthcare professionals – our hard work is catching on!

Yellow Stuff IV™ is fluid enough to fill the canal completely, but firm enough to stay put without sagging. What’s left? A flawless impression that turns into a virtually perfect earmold. We’ll leave the frustration of distortion and poor consistency to the other guys.
