This is more than likely a Pachyphytum hybrid. Those super chubby fat leaves just lead me that direction. The grower labeled it as an Echeveria but it just seems too round to be only that. In any case! These cluster very freely, most have at least a pup or two. Very pastel purple. They're so cute. Only 4 available!  No roots due to import requirements. You will receive one similar to the one shown
