This four-piece kit is designed for men who want to explore prostate play without guesswork. It walks you through a logical progression, starting with a non-vibrating beaded stimulator, moving to a suction-cup model for hands-free use, then a combo piece that pairs a prostate stimulator with a cock ring, and finishing with a vibrating massager for deeper sensation. Each toy is made from silicone and is fully waterproof, so you can use them in the bath or shower. A Dr. Ava instructional DVD is included to give you a straightforward foundation before you start. This kit is a practical choice for anyone starting from zero or looking to build a more complete understanding of what prostate stimulation actually feels like at different stages.Product DetailsToy 2 Overall Length: 4.50 inchesToy 2 Insertable Length: 4.25 inchesToy 2 Diameter: 1.25 inchesToy 3 Insertable Length: 3.75 inchesToy 3 Cock Ring Width: 2 inchesToy 3 Cock Ring Length: 1.50 inchesToy 4 Overall Length: 5.60 inchesToy 4 Insertable Length: 3.75 inchesToy 4 Diameter: 1 inchVibration Speeds: 1Power: 1 AAA battery (not included)Material: SiliconeWaterproof: Fully waterproof.
