Animal Mouth Calls
You can find other instructional videos on that website!
These are animal calls (Yes you can use them for actual hunting as well!) but many people use these when they don't want to talk in suit, and instead make little chirp/purr sounds. (Very common in the Dutch Angel Dragon community)
All calls come brand new never been used, and each has a case for transport and sanitary purposes. Be sure to wash it with some water when you finish using it.
Keep in mind these will take practice to learn how to use!
