Assorted Cactus Collection 2.5" 12 pack

Do they come in little pots like shown in the images and are they real?

What’s the best way to remove soil from the cactus? Got my order (they’re fabulous!) but in shipping, soil particles ended up covering the plants.

Anyone have any issues with their Trichocereus variety? I had 2-both were great for months but both died this week - soggy and melty and burst.

Is there a way to know, or request, cacti grown in Arizona?
