Tax included
Laser-cut wood Three-dial code It looks ready to board an ocean liner or be stashed in the trunk of an old car: ESCALE is a wooden combination chest you build yourself, engraved with a Christmas theme: snowflakes, gift packages, a reindeer, and labels inspired by a reindeer wrapping service. This 3D puzzle of 72 pieces, which takes about an hour to assemble, forms a 10.6 × 8.5 × 7.7 cm chest with a top handle, a slatted curved lid, a side latch, and three numbered dials from 0 to 9 that lock it. All parts are laser-cut from light plywood and assembled by interlocking, with no glue visible in the photos of the finished model. The manufacturer recommends it for adults and teenagers aged 14 and up. Placed under the tree, it’s a gift that can be built in one evening and then hide jewelry, a note, or an Advent calendar surprise; the rest of the year, it stores postcards and travel memories.
The proposed model
The travel trunk, a history of slats and locks
In the 19th century, the rise of railways and ocean liners transformed luggage. Trunk-makers invented flat trunks that could be stacked, reinforced with wooden slats that protected the canvas or leather from handling shocks. Curved models allowed water to run off, but could not be stacked. To discourage prying eyes in holds and stations, locks became more sophisticated, and the combination padlock, with numbered dials, gradually became common on luggage in the 20th century: no more keys to lose, just a code to remember.
ESCALE translates these two legacies into wood. The slatted curved lid evokes the reinforcements of antique trunks, while the three dials reflect the logic of a combination lock: each dial rotates a notched disk, and the latch only gives way when all notches are aligned. The laser-cut plywood, made of cross-layered plies, offers the stability needed for this adjusted mechanism, and the edge, darkened by the cutting process, creates the regular rhythm of the slats.
Why ESCALE makes you want to travel
Memory luggage
They say a journey never truly ends: it continues in the objects you bring back. A coin found at the bottom of a pocket, a stamped train ticket, a slightly blurry photo. These fragments deserve better than a shoebox. ESCALE offers them a trunk to match, scaled down for a shelf but faithful to the spirit of yesteryear’s luggage.
And because a travel trunk must be respected, this one closes with a code. The act of turning the three dials, aligning the numbers, and feeling the lock give way has a ceremonial quality, like the moment you open your suitcase upon arrival. You can choose a departure date, a flight number, or the year of your first trip together: the code itself becomes a souvenir.
Its engravings also open up another journey, that of Christmas Eve. Snowflakes, tied packages, reindeer, and "reindeer wrapping service" style labels: ESCALE looks like a trunk that fell off the sleigh, ready to guard a surprise until the morning of the 25th.

Good to know: the supplier photos indicate 10.6 × 8.5 × 7.7 cm, 72 pieces, and about one hour of assembly time, with a recommended age of 14+. The manufacturer does not, however, specify whether the combination can be changed after assembly: we therefore do not promise this.
Tip: choose a code that means something, like a year of travel or a memorable hotel room number, and write it in pencil under the bottom of the chest or in a notebook. For smoother dials, rub their axles with a pencil lead: the graphite lubricates the wood without staining it.

Keep away from fire and heat sources. Despite its handle, ESCALE is a decorative model: do not carry it while loaded by the handle, and do not rely on it to protect valuables from theft.
The Christmas gift that holds a surprise
With its engraved snowflakes, gift packages, and reindeer, ESCALE is the perfect Christmas gift: to place under the tree, to offer as a kit for an hour-long assembly evening in December, or to slip into an Advent calendar as a special box. Hide a piece of jewelry, a concert ticket, or an escape promise inside, pass the code separately on Christmas Eve, and the surprise begins before it’s even opened.
Outside of the holiday season, it remains a charming gift for a retirement, a return from travel, or a future globetrotter.

Frequently Asked Questions
How does the ESCALE chest code work?
The chest is locked using three numbered dials from 0 to 9 on the front. Each one rotates a notched disk inside; as long as all notches are not aligned with the latch, the slatted lid remains locked. When the correct combination appears, the latch releases and the lid can be lifted. It is the principle of luggage combination padlocks, reproduced here in wood. The manufacturer does not specify if the code is changeable after assembly or defined by the construction; therefore, note the combination as soon as the mechanism is in place.
I forgot my code, how can I reopen the chest?
Don't panic: with three dials from 0 to 9, there are only one thousand combinations, and the chest can always be reopened with a little method. First, try codes that have meaning to you, then proceed systematically, scrolling one dial at a time. On some disk locks, a slight pressure on the lid during rotation allows you to feel the notch align, but never force it: the thin wood could split. To avoid this scenario, write the code in pencil under the bottom of the chest or in a notebook once assembly is complete.
What is the difference compared to the combination safe in the same series?
Both models share a three-dial lock, but their spirit differs significantly. The safe is a 12 cm cube that opens with a front door once the center dial is turned, much like a bank vault. ESCALE is a more compact trunk (10.6 × 8.5 × 7.7 cm) with a top handle and engraved Christmas décor, whose slatted curved lid lifts like that of antique luggage. The former appeals to rigorous minds and fans of banking or detective themes; the latter speaks to travelers and those nostalgic for night trains and ocean liners. Choose based on the story you want to tell or the shape that best fits your shelf.
What are the dimensions of the trunk?
Based on supplier photos, ESCALE measures 10.6 × 8.5 × 7.7 cm once assembled; the capacity of the interior compartment is not specified, as the thickness of the walls and mechanism reduces the useful space. It is a small trunk, meant for a shelf or desk, suitable for small items: folded postcards, tickets, coins, small jewelry, or pocket notebooks. If you wish to store a specific object, allow for a margin or check the interior space once the box is assembled. The kit contains 72 pieces, for about an hour of assembly.
Is glue required to assemble ESCALE?
No, in principle: the pieces are designed for interlocking assembly, and the photos of the finished model show no glue. On a combination chest, this is essential, because a misplaced drop of glue can block a dial or prevent the lid from lifting. If a fixed joint of the box feels too loose, a tiny dot of wood glue is possible, at a good distance from the mechanism. To adjust a piece that is too tight, prefer light sanding of the tab rather than forcing it: thin plywood splits easily.
From what age can one assemble this trunk?
The manufacturer indicates a recommended age of 14 and up, for 72 pieces and about one hour of assembly. The assembly requires precision for the dial mechanism, patience to align the lid slats, and a degree of delicacy to avoid breaking fine parts. A curious teenager will manage just fine, and an adult will find it a relaxing hands-on moment. ESCALE can also become a shared family project, with an adult guiding a younger child on the simple steps. Just keep small pieces out of reach of children under 3 years old.
Can the trunk be personalized?
Of course. The light plywood lends itself to staining, waxing, or painting. For an antique luggage effect, stain the lid slats a darker tone than the box, like the reinforcements of old-time trunks, or hand-draw destination labels on the sides. Always apply your finishes before assembly and in very thin layers, especially on the dials and their disks: a thick coat of varnish is enough to jam the mechanism. A simple clear wax will protect the wood while maintaining its natural tone. Test on a scrap piece before you begin.
