The 12 Pack of URSA Mini Foamies Windscreens by Remote Audio is designed for smaller diameter microphones such as the DPA 6060, Sennheiser MKE1, Countryman B6, and Sanken COS11 mics. 

The Foamies are made to be rigged onto the tip of your transmitter's antenna to help reduce any RF loss that may occur when it is pressed against the body.

The windscreens are designed with flat sides so they can stick directly to the skin or a costume while providing a soft buffer to reduce clothing noise.
