The listing, 1 Cactus Start has ended.
The first photo shows the actual plant you will be getting. One of the little "buttons" as I call them. As you can tell by the ruler, they aren't very big. As you go through the pictures, you'll see how they grow. I bought these as a bunch and separated them slightly. I've had them over a year and they haven't grown much. I don't know the name of this particular plant. I have been told they are called thimble cactus or Mammillaria Gracilis. They are easy to handle without having those really annoying microscopic needles that jump into your skin from inches away and that are next to impossible to see or remove. I pick them up with my hands and no needles stick in me. They feel soft even. They have thread like roots so you'll have to water it carefully or you'll dislodge the plant.
