Decisions are hard! While we can't help you out with most of your day-to-day life decisions, we can tell you that with Zero Tolerance's Shape Shifter, you can be as undecided as you like- at least in terms of butt plug thickness!
Thanks to a ribbed silicone layer over a nice firm core, the Shape Shifter starts off (relatively) small and sleek, but can be pumped up to almost twice the thickness during play. Unlike many inflatable toys, this plug is completely wireless, and can be pumped up straight from the plug itself, or with an included remote.
Once the Shape Shifter's classic taper is in place, you can begin experimenting with size. Use the power button on the plug to cycles through 7 possible modes of vibration and incremental inflation, or sync the remote to the plug for more customized control over vibration and inflation. The Shape Shifter can swell out to a max width of approximately 2.1/5.3cm at max.
Featuring a sturdy suction cup base, the Shifter can be secured against almost any smooth, nonporous surface and enjoyed hands-free.
In ultra hygienic and hypoallergenic silicone plus ABS plastic, the Shape Shifter is body safe and conveniently low maintenance. Wash well before and after use with some warm soapy water, or use a good toy care fluid/foam. You will, of course, be using lots of lube with this toy, so be sure to choose a good quality water-based formula. Please don't be tempted to use a silicone lube- it could break down the material. USB rechargeable, charge cord included. Remote requires 1 CR2032 battery, which is included. The Shape Shifter is splash-proof, but should not be fully submerged.
