Material and safety you can trust

Crafted from Tantus' exclusive 100% Ultra-Premium Silicone, these O-rings are body-safe, hypoallergenic, and hygienic. Silicone ensures a smooth, comfortable seal with minimal friction, so you can focus on the sensation rather than the setup. The set is designed to be boilable, bleachable, and dishwasher safe, making maintenance quick and effortless between adventures.

Why this set stands out

• Versatile compatibility: Works with any O-ring–based harness, letting you adapt to your toy of choice without swapping whole harnesses.
• Transparent progression: The six sizes cover a broad range, so you can tune the fit for different Tantus toys and user preferences—tight for precision, looser for relaxed wear.
• Durable, body-safe silicone: Smooth insertion, easy cleaning, and long-lasting performance for frequent play.

Practical use cases

Pair the O-Ring Set with your favorite Tantus toy to optimize grip, seal, and stability during play. Ideal for solo sessions that require a secure fit, or couple play where shared control benefits from a consistent, comfortable hold. If you’re experimenting with different toys or harness configurations, this six-pack removes the guesswork and helps you quickly dial in the right sizing for peak sensation.

Care tips and safety notes

• Always follow the “do not use O-Rings on penis” warning—this set is designed for toy use only.
• Clean before and after use with mild soap and warm water, then boil, bleach, or run through the dishwasher when appropriate to sanitize.
• Inspect rims for nicks or tears; replace if any damage is found to maintain a secure seal.
• Store in a clean, dry place away from sharp edges to preserve smoothness and elasticity.
