Montblanc gives no official quantities on these Special Editions, so only estimates are possible; the editions of "Jungle Eyes" and "True Princess" lie presumably below those of the Writers Edition, since the expensive pieces sold worse. Particularly rare is the White Pearl Edition, since it was never officially offered and is moreover the only Meisterstück without the three cap rings; it was initially delivered only in Germany. The stones used in the Jungle Eyes editions are: green = tourmaline, cognac = Madeira citrine, yellow = Palmeira citrine, purple = amethyst, blue = topaz; white (mother-of-pearl) and black (onyx) belonged to the Gift Collection 2004. Mozart sizes are overall rarer to encounter than the 144 sizes.
