This Blank is: a sea colored with a dark brown accent. like looking right own at the sea floor! 
This blank is 3″ long by 1.5″ diameter. It has a 5/8″ hole on one end and a 7/8″ hole on the other meant to be used with a gutsert. These goose call blanks do not require any drilling to make a goose call.
If you want to turn a blank down, to fit into the 7/8″ end with o-rings and not using a gutsert, you can use one of our duck call blanks which has a straight through 5/8″ hole.
