This relatively slim, hollow plug is a more manageable choice for newcomers and novices to urethral penetration, it's shaped for smooth, comfortable insertion thanks to the firm, excitingly firm stainless steel tip and the silky, flexible texture can be easily manoeuvred into place. Adding to the experience, your choice of two stainless steel rings placed on a stabilizer at the base keeps a firm hold around the head of the penis, simultaneously providing a deliciously unrelenting pressure

Made from hygienically superior silicone and high-end stainless steel, the Inertia can be fully sterilized, an absolute must-have feature in any urethral toy

The Inertia is available in 2 lengths:
Short: 95mm (3.75 inches) long insertable
Long: 180mm
while the steel tip is a mere 5mm (0.2 inches) wide for ultimate comfort.

A sterile, one-time use medical grade lubricant is recommended for the Inertia, and any urethral penetration tool, for that matter.. On that note, be sure to follow sterile procedures during cleansing and use for your safety and comfort. Simply avoid abrasive surfaces and silicone lubricants to keep this tool suitable for years and years of enjoyment.
