It is a three-dimensional puzzle that creates a secret treasure chest with three dials, each of which must match to open.

There are two sizes: large and small, and this is the large size.

It looks appealing to children, but the real excitement is when you turn the dials to open it—truly a treasure chest.
You can store your favorite items, game software, or New Year's money, and enjoy the feeling of exclusivity knowing only you can open it.


There are various ways to use it.
As a small item storage or piggy bank.
Because it is a natural wooden treasure chest, it naturally blends into a child's room.
It exudes a sense of secrecy.
It will definitely catch your friends' attention.
Since it is a large size with plenty of storage, you can also store accessories or small keychains received from friends as tokens of friendship.

The three-digit password combination has 10 x 10 x 10, totaling 1,000 possibilities.
Also, because it is made of wood, you can freely draw or decorate it to create a one-of-a-kind original treasure chest.


Made with safe natural wood and laser engraving, using high-quality natural wood.
When opened, the fragrant scent of wood wafts out.

Since no paint is used, there is no risk of trouble from direct skin contact.
Painting is also free to do.

Because it uses computer-controlled technology capable of precise cutting to the hundredth of a millimeter, the finish is uniform and smooth.

Sometimes, the cut surface may have a slightly burnt smell, which is also a characteristic of wooden puzzles.

Slight charring and diverse wood grain patterns are unique to wood and are part of the charm.


Includes five large sheets of wood.

Based on customer feedback, since 2022, the packaging has been changed to include a cover page and improved packing methods.
Making it easier to give as a gift.

There may be slight differences in folding or orientation, but the contents are the same, so please understand in advance.



Includes a Japanese instruction manual for peace of mind.
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 what to do, so detailed instructions are provided.

However, if all of this is done by a guardian, the effect of the dial lock is lost, so it is better if the child proceeds without knowing the code, which will also bring joy to the child.


A series of educational toys that bring joy in creation and continued enjoyment afterward.
We offer products that even beginners or those inexperienced with wooden puzzles can confidently assemble and enjoy after completion.
All come with Japanese instruction manuals.
We guarantee the creation of successful experiences for children.


*Difficulty is set assuming children will make it.

Because the three-digit dial lock must match to open, it is ideal for storing secret items or treasures.
The dial combination has 10 x 10 x 10, totaling 1,000 possibilities.

This is the large type with 82 pieces, and the finished size is 15.6 x 12.1 x 10.6 cm.
It blends seamlessly into living rooms or study rooms.

Made from natural wood, ensuring safety and peace of mind.
Since painting is possible, you can also create a one-of-a-kind original treasure chest.

Includes an original Japanese instruction manual, so although the dial part is slightly difficult, anyone can complete it if they proceed carefully.
The excitement reaches its peak as you get closer to completion.
It is purchased by many customers as a gift for cram schools or after-school programs.
Please consider using it for celebrations or events.
