These are a small friction call that can do everything a box call can, but in a smaller package. They are 3 x 1 x 1 . The body of the call is hardwood. I generally use maple but can use any hardwood you desire. The sound board is either Poplar or Red Cedar. The Poplar gives a nice medium pitched, raspy call. The Red Cedar is a higher pitched call with less rasp. Each call comes with a Poplar striker. Each call is $15.00.
