This is a three-dimensional puzzle that creates a secret treasure box with three dials, each of which must match to open.
There are two sizes, large and small, and this one is the small size.
The parts are small, and the increased detail work makes it more difficult than the larger size.
Particularly, areas that require force are more prone to damage, so we ask for parental assistance as much as possible.

From its appearance, it appeals to children's hearts, but turning the dials to open it is truly exciting—like a treasure chest. You can store your favorite items, game software, or New Year's money, and enjoy the feeling of having only you able to open it.


There are various ways to use it.
As a small item storage or piggy bank.
Because it is a natural wooden treasure box, it blends naturally into a child's room.

Its cute small size makes it suitable for any place, and it can store small accessories, keychains, or New Year's money.

The three-digit password combination has 10 x 10 x 10, totaling 1,000 possibilities.
Since it is made of wood, you can freely draw and customize it to create a one-of-a-kind original treasure box.
Recommended as a pair set of large and small for parents and children or couples.

Made with safe natural wood and laser engraving; no synthetic or waste wood is used.
No paint is used, so there is no risk of skin troubles from direct contact.
When opened, a fragrant wood aroma wafts out.
Using computer-controlled technology that cuts with millimeter precision, the finish is smooth and even.
In extreme cases, two parts can be swapped without any problem in the manufacturing process.
The cut surfaces may have a slightly burnt smell, which is characteristic of wooden puzzles.
A slight charring is natural for wood, and it adds to the charm of the product.


The product packaging and size are as shown in the diagram.
Includes five small wooden boards.
Based on customer feedback, since 2022, the packaging cover has been added and the packaging method has been changed.
The appearance has been improved, making it easier to give as a gift.
Please enjoy it together with other series.


Comes with a Japanese instruction manual for peace of mind. The image shown is for catalog purposes; it differs from the actual product, but a Japanese instruction manual has been created through monitor testing and is included.
The most difficult part is the dial section, which is very challenging for small children to do alone.
Even adults may initially be unsure of how to proceed, so detailed instructions are provided.
However, if parents do everything for the child, the lock's effect is lost, so it is best to proceed while pretending not to know the code, which will make children happy (verified). We hope all purchasers will be satisfied with the puzzle and enjoy it.


A series of educational toys that bring joy in creation and continued fun afterward.
We offer products that beginners and those inexperienced with wooden puzzles can confidently assemble and enjoy even after completion.
Includes a Japanese instruction manual for peace of mind.
We promise to create a successful experience for children.


*Difficulty is set assuming children will make it.


Customer feedback—
I ordered it thinking it would be a good craft for summer vacation, but I was a little worried whether I could make it (or teach it), but the detailed instructions allowed me to complete it successfully.
Since it is not a kit, I couldn't have made such a detailed wooden box otherwise, so it was a very good experience.

I also like the cute exterior design.


Made it as a summer vacation craft with my child.
As a three-dimensional puzzle, it was quite difficult.
Nevertheless, they patiently worked hard to make it.
The dials are not just decorative; they turn properly, showing a well-made design.
It gives a sense of achievement.
Since the wooden boards are thin, I wondered what to do if they broke, but spare parts were included.


As an educational toy, I gave it to my second-grade grandson.
It has 82 small detailed parts, making it quite satisfying to assemble.
He was engrossed while looking at the assembly instructions.
Because it is a wooden 3D puzzle, it stimulates intelligence and creativity.
The wooden material gives it a high-quality feel.


It is very exciting and thrilling to open the box with your own secret number.
The assembly is somewhat difficult, but watching over what children can do and subtly guiding them to complete it created a very good parent-child time.
It can hold small items, so it is used as a treasure chest.
Since it is a three-digit dial lock that only opens when the combination matches, it is perfect for storing secret items or treasures.
The dial combination has 10 x 10 x 10, totaling 1,000 possibilities.

The small type has 77 pieces, and the finished size is 10.6 x 8.5 x 7.7 cm.
It blends naturally into living rooms or study rooms.

Made from natural wood, ensuring safety and peace of mind.
Since it can be painted, you can also create a one-of-a-kind original treasure box.

It comes with our original Japanese instruction manual, so although the dial part is somewhat difficult, careful assembly will allow anyone to complete it.
The excitement reaches its peak as you get closer to finishing.
Many customers purchase it as a gift for cram schools or after-school programs.
Please consider using it for celebrations and events.
