Description: 

Gymnocalycium mihanovichii is a species of cactus from South America. 
The most popular cultivars are varied mutants which completely lack chlorophyll, exposing the red, orange, or yellow pigmentation. 
These mutant strains are often grafted onto cactus, and the combined plant is called a "Moon Cactus". 

Moon cacti are commonly grown as houseplants and are also known as Ruby Ball, Red Cap, Red Hibotan, or Hibotan cacti.

I will ship in a bag to contain the soil within the pot. Some soil may become loose during transportation. This is not an issue for the health of the plant.

Upon receipt, plant in a pot (Or enjoy as is for the time being).
