I was delighted to receive your missive this evening, I am honoured to hear that Master Mitchell would be interested in owning one of the Miniature Marvels(tm).
As of now, we are offering three breeds, The Grey Welsh, The Icelandic Smoothback and the Moroccan Smoothback, for immediate purchase. If there is a different or unique breed or colouring Master Mitchell would prefer to own, you need only write back and let me know. Within reason, we can breed a custom Miniature Marvel(tm) to suit his wishes.
The only cautionary note to relay is that the Grey Welsh, along with most other breeds of Miniature Marvel (tm), is still equipped with its natural defense mechanism (fire, lightning, et al.) Each breed of Smoothback, as you may know, is equipped only with an exoskeleton and exceedingly sharp teeth for protection. Should you wish to purchase any breed other than a Smoothback, you will have to sign a waiver indicating your understanding of the possible (though minimal) dangers.
Additionally, investment in DMM INC. is currently tax deductible, per MoM regulation code 181302354532MCC, or the Magical Creature Creation Expenditure Code. If you should still desire to invest in DMM INC., I would be more than happy to owl you the necessary tax documentation.
Thank you for your business,
Dr. Charles A. Weasley, PhD of Dragonologic Experimentation and Genetic Mutation.
