My wife works in the health/wellness/weight loss field, and this is just the ticket, to illustrate what 5 pounds of ugly fat looks like. If your goal is to show people what 5 pounds of fat, all in one ugly lump looks like, this is your product.
It isn't the easiest thing to clean, as it has an uneven 'rubbery' type surface, that seems to catch and hold dirt/grime, but warm soapy water seems to do the job.
It seems kind of pricey, for what it is, but if you are wanting an anatomically correct fat replica, I don't know where else you could get one.
