Girth Enhancer Kit: Each kit comes with four (4) uniquely sized premium soft rollable silicone tubes. Each tube can help increase the girth of your penis to fit into a model with a larger hole size. The tubes can be rolled onto the penis, similar to a condom.  For instance, if your penis girth measurement is 3.5″ and your preferred model has a 4.5″ girth hole, you can roll the soft appropriate tube(s) onto your penis. The enhancer will allow you to insert yourself into the sleeve for a snug fit (some lubrication may be necessary).. Individual Girth Enhancer tubes are sold separately and are found under accessories.

Adjustable Inner Rod: The insertable silicone rod can act as an erection aid to fill the air gap between the head of your penis and the end of the sleeve.
