Wooden boxes that ship flat and take 80% less space in your warehouse
Forget storing pre-assembled boxes that eat up your warehouse. Sincla boxes ship flat-packed, assemble in 20-30 seconds and keep the rigidity and premium look of a traditional wooden box.
The hidden cost of traditional wooden boxes
A standard pre-assembled wooden box takes 5 to 10× more space than its flat-packed equivalent. 100 assembled boxes need three pallets; 100 flat-packed Sincla boxes fit in less than half a pallet. That overhead shows up everywhere: more freight trips, larger warehouses, higher handling risk and bulkier secondary packaging. For a brand shipping thousands of units a year, that means hundreds — or thousands — of euros lost every month. Sincla solves this without giving up the natural wood finish: our boxes use a precision tab-and-slot system that ships flat and assembles in seconds when you need it.
How we make flat boxes that look factory-assembled
Not a generic flat-pack. An industrial design built from scratch so the flat format never compromises rigidity or aesthetics.
- Poplar 3 mm, calibrated to under 0.2 mm tolerance so tabs always click in first try.
- No screws, staples or glue: parts lock together by friction and geometry.
- Finish identical to a factory-assembled wooden box: sanded edges, clean corners, exposed wood with no visible hardware.
- Compact pallet shipping that cuts logistics cost up to 5× vs. traditional boxes.
- Fully compatible with laser engraving, color printing and custom die-cuts.

Frequently asked questions
Do boxes warp while stored flat?
No. Treated poplar keeps its shape indefinitely. A box stored flat two years ago assembles just as well as a fresh one.
Are they rigid once assembled?
Yes. The tab-and-slot system works like a mechanical joint: the box stays firm and supports typical product weight (up to 3 kg per format).
How much does shipping save vs. assembled boxes?
Savings on shipping typically range from 50% to 70%, because 3 to 5× more product fits in the same truck.
Can I keep some assembled if I want?
Of course. Many customers assemble a first batch to have ready and keep the rest flat until peak demand.
Does it work with laser engraving?
Yes. Personalization is done on the wood before final cutting, so the result is identical to a factory-assembled box.
