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.

Really unimpressed

Package came completely damaged from the toy cleaner, everything is soaked. My grinder is pink instead of red despite checking before purchase and isn't similar to the design reference I sent at all. the toys are good quality though

Best seat in the house

I’m new to using toys in the bedroom but decided to try something new. I looked at reviews and asked questions (customer service has been really great) and decided to buy the oni grinder. He was worth the money! I added the bullet upgrade, which was a great move on my part. I forgot to charge the batteries last time and it stopped when I was about 2/3 through (nooo 😮‍💨😭) and it was then that I realised that the bullet definitely heightened the experience. He’s great to grind against on his own, but the vibrations from the bullet are just *chef’s kiss* amazing 😻 I just turned on the vibrator and sat on him once and ooh! was that ever nice! I love that tongue texture in particular but he’s got quite a lot of good points and I am going to thoroughly enjoy finding each one.
I’ve only used him three times so far and I’m already looking at buying another grinder from this company. I didn’t get the silky smooth upgrade, but I think I will definitely get it for my next toy. I love the soft firmness that I got, but I think that the silky smooth upgrade will be worth getting. I didn’t know what to expect, so I was pleasantly surprised by how hefty he is. Although he has straps, I don’t think he’s going anywhere. He’s quite solid. I was a little worried that he might be a pain to clean, but I haven’t really had any problems yet. The toy cleaner I bought with him works quite well.
I paid extra for the UC trademark colours, and it looks even better in person. My monitor appears to show the colours darker than they are in person, so I was pleasantly surprised by how he looked. I like to poke and squeeze him a bit whenever I walk by him. I would squeeze him more, but I don’t want to risk damaging him. It’s probably a silly worry since he is so solidly built and will probably last a very long time. I don’t have him hidden under the bed but have him near my computer. He’s too beautiful to hide under the bed in a box all the time.
In conclusion, I am very happy with my purchase, and I will definitely come back again. Uncover Creations, you have earned yourself a loyal customer.

Feels great!

I love the aesthetic of this one so much, and wish I sprung the few extra bucks to get the IG design color. I got Medium firmness and it honestly feels just like receiving oral, I am in love. You can grab it by the horns and go wild. Highly recommend.

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 :/
