The plug that does more than just sit there.

Prefer to be in charge? The onboard buttons give you full control of the action. Want to kick back and enjoy? The wireless remote lets you switch things up without breaking the mood. The whisper-quiet motors keep things discreet, so your pleasure stays your business.c

It’s also a breeze to clean. A little warm water, some mild soap, and you’re good to go. Plus, with a magnetic charger, you’ll never fumble with annoying cables. With an IPX5 waterproof rating, it can handle some splashes, making shower-time play an option, but keep it out of deep water (save that adventure for another time).

W.O.W

"Perhaps a bit intimidating to newer people to anal but with patience it fills you nicely. The vibrations aren't the strongest but they're quiet and powerful enough, the beads are what sets this apart from anything else I've experienced. Can just sit back and enjoy the pleasure without any other stimulus and still be breath taken at the end. Thoroughly recommend the product and company!"

A new favorite!

"This is the best vibrating and rotating didlo butt plug. Once inserted gives the best feeling and leads to an amazing finish. And the different intensity and speeds are really good. Have never been happier 😊👍"

Pow-mazing

"Comes beautifully presented in an attractive little gift box. The product itself is very good quality and is made in a silky smooth rubber. It was easy to insert and comfortable once inserted. It gave a pleasant sensation. I do like a sex toy and have had quite a few over the years. This is definitely a good one."

Kyle K.

Verified Customer

Awesome!

"I recently purchased the Onyx butt plug to try on my partner as we have sex or watch him use it on himself whilst masturbating. This is a must for anal pleasure and will be definitely making further purchases of similar items. This is versatile. Can be used alone or on your partner and the vibration settings for a small plug are extremely powerful."

Mind blowing

"Nothing to dislike about this. It is large so it will give you a challenge to get it in but when you do it stays in place and feels oh so good. Remote works great and battery life gives you plenty of time to play."

Lewis H.

Verified Customer

OMG 😊👍

"Yes, it's a little big, but if you are not new to this type of toy you will not have any trouble getting it in. The rotating bead feature makes this toy, and I discovered a technique to a great orgasm using the remote. When you're close, turn the vibration mode on steady to the medium speed, and then turn the rimming feature on full speed, then start reversing the direction of the rimming every two or three seconds. Reversing the rimming direction back and forth over and over really feels great."

While researching men's toys, we noticed that most were made from generic plastic and lacked unique features. Since we already had several stores in other markets, we thought, why not create something better for men? That’s how we developed the Cosara Flesh, which has quickly become one of the best sellers in America.
