Why You’ll Love It
The Vixen KnightFit Vibrating Sleeve is made to add fuller size, extra texture, and vibrating pleasure to couples play. Its ultra-stretchy design slides on easily and adds approximately 45% more girth for a thicker, more satisfying feel.
The ribbed multi-ring design creates added friction and stimulation for your partner, similar to the sensation of a textured condom but with a fuller, more substantial feel. A removable mini vibrator adds buzzing stimulation to heighten every stroke.
Made from soft, body-safe TPE, KnightFit feels flexible, realistic, and comfortable for both partners. The material is latex-free, phthalate-free, durable, and designed for repeated use without losing shape.
The waterproof sleeve is easy to clean with warm water or soapy water, making it a simple, exciting upgrade for couples who want more girth, more texture, and more shared sensation.

Safe, Clean, and Body-Ready: The Vixen Material Promise
Your body deserves the best. That’s why we prioritize:
Medical-grade silicone: Non-porous, hypoallergenic, easy to clean.
ABS plastic: Durable, smooth, and body-friendly.
Borosilicate glass & stainless steel: Great for temperature play, ultra-hygienic.
Phthalate-free TPE/TPR: Used in some realistic strokers for ultra-soft texture.
Every product page includes clear specifications for materials, cleaning instructions, and compatibility with lubricants. Most of our toys pair best with water-based lubricant, ensuring safety and longevity.
Easy Maintenance: Clean, Store, Repeat
Keeping your toy clean ensures long-term pleasure and safety. Here’s how we recommend caring for your toy:
Before and after use: Wash with warm water and unscented soap or use a toy-safe cleaning spray.
Electric toys: Wipe with a damp cloth and mild soap. Never submerge unless 100% waterproof.
Non-electric silicone/glass/metal: Many are boilable or top-rack dishwasher-safe.
Storage: Keep in the included pouch or separate from other materials to avoid reaction.
Clean toys = safer, better, and longer-lasting play.
Designed for Every Body
We’re proudly inclusive. Vixen toys are for:
Women, men, nonbinary & trans customers.
Solo adventurers and curious couples.
All sexualities and experience levels.
Beginners and pros alike.
From petite beginner plugs to dual-ended dildos, vibrating cock rings to prostate massagers — we make sure everyone finds their fit, their fantasy, and their freedom to explore.
Let’s Talk Compatibility
We get questions like “Can this be used with a harness?” or “Which lube is safe for this toy?” all the time — and we answer those directly on each product page.
Here are some general rules:
Water-based lube = universally compatible.
Silicone lube = only safe with non-silicone toys (like glass, metal).
Strap-on harnesses = check for a flared base or O-ring compatibility.
Condoms = always a good option for shared toys or porous materials.
99% of Vixen’s product pages includes size, fit, and usage notes to take out the guesswork.
Discreet Packaging. Secure Checkout. Private Satisfaction.
Your privacy is non-negotiable. All orders are shipped in plain, unmarked packaging, and our name never appears on the outside.
No logos.
No giveaway product names.
No one will know what’s inside but you.
Payment is secure, billing is discreet, and your details are protected. That’s our promise.
Questions? We’ve Got You Covered.
Are your toys safe?
Yes — all toys on Vixen are made from body-safe, non-toxic materials. We never stock cheap, unsafe, or low-quality items. Each listing includes detailed materials info, and we third-party test everything for comfort and durability.
How do I choose my first toy?
Start simple. Bullet vibrators, smaller dildos, or soft strokers are great intros.
Can I use this toy in the shower or bath?
If it says waterproof — absolutely. Just look for the “Waterproof” or “Fully Submersible” icon on the product page. If it’s “Splashproof,” stick to dry areas. Please note: While many of our toys
are labeled waterproof, we do not recommend submerging any electric toy for extended periods. Always exercise caution to preserve battery life and internal components.
What is your return policy?
Due to the nature of intimate products, we don’t accept returns of opened items. But if something arrives damaged, defective, or not as described, we’ll replace it or make it right. Just contact our support team within 30 days.
Will anyone know I bought a sex toy?
Nope. Your order ships discreetly and your billing statement uses a generic business name. Your secret is safe with us.
