The Vibrating Stiffy range delivers a solid, rigid feel for strong pressure and penetration, with a textured shaft and prominent head for lifelike sensation. Dimensions published by retailers show about 12″ overall length with 10″ insertable and roughly 2″ diameter, giving a very full experience.
Key features
10″ insertable length with approx. 2″ diameter for fullness.
Multispeed vibration via base control; realistic sculpt.
Body‑safe, phthalate‑free PVC; many listings indicate waterproof design.
How to use
Apply water‑based lubricant generously for comfortable glide with firm PVC.
Start on low speed and increase as desired; the firm shaft provides consistent pressure for G‑/P‑spot angles.
If using in the shower, verify your unit is labeled waterproof and keep the battery cap sealed.
Lube guidance
Use water‑based lubes with PVC; avoid harsh oils or alcohol‑based products that can damage the material.
Cleaning and care
Wash the shaft with warm water and mild soap or a toy cleaner after every use; keep water away from battery compartments if not fully waterproof.
Air‑dry completely and store in a pouch away from other toys and heat.
Wellness benefits
A rigid, long shaft plus steady vibration supports deep, targeted stimulation and consistent pressure, reducing arm fatigue during longer sessions.
