Fabrication Enterprises Physiogymnic Inflatable Exercise Ball

Mine came quickly and I inflated it with one of those vacuum pumps for rafts and air mattresses. It's heavy vinyl and seems to be very well made. As far as the sticky substance? That has to do with the forming of these things. For the price, I do not mind cleaning it myself. After it was inflated, I cleaned it with Windex and a rag. Sticky all gone. Dawn would also clean it well.This ball is sold for much higher prices by other sellers. It's the same ball as the higher priced ones. I am glad I took the risk. I saved a bunch.
