WHITE PEACOCK! Cacti Hybrid (Ortegocactus Macdougalii?)

These cacti might be my favorite yet. They are almost solid black in person and the single looks exactly like a sea urchin. She's incredible, was so tempted to keep this one. She will ship tomorrow 2-day and will be there by Monday. You can request a shipping hold if you are away. 

Fairly certain these are a Macdougalii hybrid. I have one in my collection and these look very similar, just more of an onyx skin. These are going to be super small and unfortunately due to their rarity and cross they are very pricey. There are two options available, a single and a double.

The single is measuring in at about an 1.25" across.

Double is measuring in at about 1.75" across.
