Description:

Fully in pure platinum 999% (malleable and well-tolerated material).
The loop has 3 grooves: with a light pressure of the forceps the grooves allow an equal and soft crimping, diluting the pressure on the long apophysis of the incus without causing necrosis because of overcrimping.

The spherical edge of the stem provides a delicate contact between the piston and the new oval window membrane.
