An isohedral D4 based on a scalene tetrahedron. The four faces are identical scalene triangles with sides 35.5 mm, 32.3 mm, 24.5 mm. Hollow pipped version, wall thickness 1.3 mm. Roll the die and read the number on the landing side. Note: Any resemblance to real slices of cheese, living or dead, is purely coincidental :).
