Knox combines controlled inflation with a built-in fluid-release function in a single structure. Made from premium Liquid Silicone, the red body features an internal channel that allows fluid to be released through the tip, adding an interactive visual element without the need for electronic components.

The curved, canine-inspired shape includes an inflatable knot section that can be adjusted in size and firmness through manual inflation. As the knot expands, it creates concentrated internal pressure and a strong filling effect, making Knox suitable for experienced users seeking advanced expansion and targeted internal positioning.

Key Features

• Dual-Function Construction
  Integrates inflation expansion and fluid-release capability into one non-electric design.
• Inflatable Knot Structure
  The central knot expands through air inflation, allowing for controlled adjustment of fullness and pressure.
• Liquid Silicone Material
  Crafted from smooth, flexible Liquid Silicone for durability under inflation and fluid use.
• Manual Pump & Valve System
  Provides precise control over inflation and quick deflation when needed.
• Wide Safety Base
  Flared base ensures stable positioning and reliable external control.

How to Use

• Step 1: Clean Before Use
  Rinse the product thoroughly with clean water before first use and after each session.
• Step 2: Apply Lubricant
  Apply a generous amount of water-based lubricant to the surface for smoother insertion and better comfort.
• Step 3: Connect the Tubes
  Ensure the air pump and liquid tube are correctly installed and securely connected before use.
• Step 4: Inflate Gradually
  Tighten the valve clockwise, then gently press the air pump to inflate slowly.
  To deflate, rotate the valve counterclockwise to release air.
  Inflation can be adjusted during use for controlled expansion.
• Step 5: Liquid Injection Function
  Use a syringe or squeeze bulb to inject liquid (water or other suitable liquids) through the built-in channel to activate the squirting function.
• Step 6: Suction Cup Play
  The strong suction cup base allows attachment to smooth surfaces such as tiles or glass, enabling hands-free and multi-angle positioning.
