Note : picture is a file picture rather than the actual as waiting on it's arrival

This is a 1/2" (12.7mm) thick block in the standard 50mm width with a variety of depths:

Custom size option for deeper guitars

These weigh about 50% more than the original brass blocks they are designed to replace
