Description

Introducing the Oni Grinder, a sensual masterpiece where sharp, fierce design meets soft, silicone pleasure. Inspired by the Oni of Japanese folklore, this grinder boasts devilish details, including textured horns and a sinuous tentacle tongue that teases and tempts with every move. The cherry blossom base adds a delicate, unexpected touch, balancing strength and beauty in one captivating design.

We loved designing this beast, and we can’t wait to get it out into the world and start experimenting with all the exciting color combinations you choose.

Whether you're strapping it to a pillow, your thigh, or even your forearm with its fitted black nylon straps (2.5ft / 0.7m each) and quick-release buckles, this grinder will have you in for one hell of a ride.

And for those who like things a little smoother, you can upgrade your Oni Grinder with our Silky Smooth Upgrade, offering a buttery glide thanks to an additive derived from Durian tree nuts. Just be aware of the slight nutty scent, and people with a nut allergy should avoid this option.

Award-Winning Pleasure That Finally Slayed The Dragon

Yes, we're legally required to mention our Oni Grinder won the Bazowie Awards 2025 "Best Horror Toy" (we beat Bad Dragon, and no, we will NOT stop bringing this up at every opportunity). After years of being the underdog, we've officially graduated to "the company that slayed the dragon." Is this our villain origin story? Perhaps.

I love him!

The Oni is a fantastic toy, and I am so glad I got it! The design is stunning, and the pour on mine is beautiful. The tongue, nose, and horns work well for both external stimulation and penetration, and the textures all over are great. The forehead is especially nice for grinding, and he's pretty heavy, so he stays wherever you put him. Definitely one of my favorite toys!

Disappointed 🫤

This oni was a remake after my original order arrived with a flaw — my original colors were pink, thistle, purple— soft pastel colors. I requested a purple strap. Just really not a fan of these colors and disappointed that there wasn’t extra care put into the creation process of this remake :/

The Oni Grinder is my first toy of this kind and I’m surprised in a positive way! It can be used in many different angles and positions and with the Liquid Silk instead of only waterbased lube it feels really good. I bought it in squishy soft and this was definitely the right decision. And the UC trademark colors in Sangria/Moonkissed instead of red/black look so cool!

Easy Favorite!

Toy: This is my first grinder and purchase from UC. For me, there was a bit of a learning curve and experimenting with placement to get the most out of this toy. Once I figured it out, it was a smooth ride 🤤 The super soft firmness is perfect; I don't believe the squishy soft would've given me the desired result. Definitely check out the firmness guide! I'm also really glad I upgraded to silky smooth. I don't have to add any extra lube to help reduce friction; I'm practically gliding lol. There is a nutty smell, but it wasn't overpowering thankfully. The facial features and tongue are perfectly placed and I honestly can't complain lol 👀 I wish I'd gone with a darker brown and chosen my color arrangement better, but that's purely a "me" problem.

Customer service: *chef's kiss* Very patient with me! I greatly appreciate that, especially since this was my first time ordering a customizable toy and I was all over the place with my request. Email responses were prompt and polite. Thank you 🙏

Overall, 10/10! Y'all have a new repeat customer. I already have my eye on a couple things 👀 💖

The ONI one for me ♡

Absolute LOVE this toy!! It's so soft, easy to use and gives a fair few ways to use it. I'm disabled and have mobility issues, but this Oni grinder is easy to use for that much desired stimulation! Hold the horns and let the tongue explore, slip in a horn and grind the nose, or rub its face everywhere, the options are boundless :D
