Mr. Kikuchi's Note
Mr. Kikuchi's Note
Caldera did not begin as our completely original shape.
I had seen similar forms used successfully for gape training, and the basic idea already made sense: a short body that keeps getting wider instead of giving the width back too early.
We adjusted the proportions, firmness, surface details and finish until it felt like something that belonged in our line.
Sometimes design means inventing a new shape. Sometimes it means recognizing a shape that already works, then making your own decisions about how it should feel.
That is Caldera.

Taking something huge is one kind of satisfaction. Seeing the result afterward is another.
Caldera keeps the width present for sessions focused on gape training—not just getting it in, but working toward the fuller, more open look you want to see afterward.
Train the gape. See the result.

Need help choosing the right size?
Please check the size chart above carefully before ordering. If you are between two sizes or unsure where to start, we recommend choosing the more approachable option first.
If the measurements feel confusing, please read Mr. Kikuchi’s Size Guide first. You can also contact us on directly here.
What are Kikuchi Toys made of?
All Kikuchi Toys are made with 100% platinum-cured silicone.
It is non-porous, body-safe, and easy to clean with warm water and mild soap.
What is Kikuchi DualDensity™?
Dual density means two silicone firmnesses in one toy: a softer entry & outer layer with a firmer supportive core.
Compared with other structures, Kikuchi DualDensity™ Silicone Design allows the head to stay very soft without making the whole toy too floppy. The softer tip and surface make first contact gentler and less poking. The firmer inner core gives the toy enough support to enter more smoothly, stay in place with less slipping out, and move with better control.
If one Kikuchi Toy uses two silicone densities or more, it will show DualDensity™ firmness.

Can I request a different firmness or color?
Customization depends on the product.
Some Kikuchi designs can be adjusted during production, while others use a fixed firmness or color because that configuration is part of how the product is meant to perform.
The options shown on each product page are our recommended configurations. If a product uses a fixed setup, you’ll see that noted in its Structure section.
For products that allow customization, please read our Firmness & Customization page and contact us before ordering.
Do you ship worldwide discreetly?
We ships internationally to supported destinations and your privacy matters.
Your toy will be shipped in a plain, unmarked box with no product names or adult branding on the outside.
For more details, please read our Shipping Info page.
Can I return or exchange my order?
Due to the intimate nature of our products, we do not accept returns or exchanges once an order has been shipped.
Exceptions may apply only if the toy arrives defective, damaged, or in the wrong size/product. If there is an issue, please contact us at support@kikuchitoys.com within 7 days of delivery.
