Black Inflatable MEDIUM LATEX ACCORDION with Pump Please READ this entire listing: This is not a sophisticated product.  It is labor intensive to make, ie: hand assembled, thus the price, but basically it is a balloon mounted to a base.  As such, it will act like a balloon when inflated and nothing more should expected from it.  It is a balloon and balloons can't be trained to inflate in a certain way. RIBBED LATEX ANAL PLUG Non-Inflated measurements: Length 30.5cm - 12.0 Inches Diameter 6.4cm - 2.5 inches Girth 20.3cm - 8 Inches It is inflated with a bulb pump that is connected to a approx. 10" tube. Made of standard molded latex/rubber with a thickness of about 0.020", 0.50mm We import these directly from the manufacturer; they are made of pure BLACK latex rubber. If this is an inflatable item it will safely inflate to "about" double girth and length will change slightly. Since they are like a balloon they will conform to whatever space it has been inserted into, and how it appears inflated in your hand will not represent how it looks when in use.
