Setup & Assembly
Your ROKR Treasure Box kit contains 123 precisely laser-cut wooden components. No glue is required for assembly, as pieces are designed to fit together tightly. Some light sanding may be necessary for optimal fit and smooth operation of moving parts.
Follow the detailed pictorial instructions included in your kit for step-by-step assembly. Pay close attention to the orientation of each piece and ensure all connections are secure. The assembly process is challenging and may take several hours, depending on your pace and experience.

Setting the Password
The unique three-digit password for your treasure box is set during the assembly process. It is crucial to carefully follow the instructions provided in the manual for this step, as the password is fixed once the assembly is complete and cannot be changed afterward. Make sure to record your chosen password in a safe place.
Operating the Treasure Box
Once assembled, your ROKR Treasure Box offers two primary functional mechanisms:
1. Opening the Main Compartment
To open the main compartment and access the inner tray, you must correctly input the three-digit password you set during assembly. Once the correct combination is aligned, insert and rotate the key located at the back of the box. This action will unlock the mechanism, allowing the top lid to be lifted and the inner tray to rise.

2. Activating the Top Blooming Mechanism
The top of the treasure box features a decorative gear. By rotating this gear, you can activate a unique mechanism that causes the internal elements to open, resembling a blooming flower. This reveals an additional small space for display or storage.

Maintenance
To ensure the smooth and consistent operation of your ROKR Treasure Box's mechanical parts, it is recommended to periodically apply a small amount of wax to all articulated (moving) pieces and gear teeth. This lubrication helps reduce friction and prevents sticking.
Use a soft cloth or cotton swab to apply a thin layer of wax. Ensure that wax does not accumulate in areas where it might impede movement. If your kit did not include wax, a standard candle wax can be used as an alternative.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Lid or internal mechanism sticks/does not move smoothly. | Lack of lubrication on moving parts; tight fit of components. | Apply wax to all gears, hinges, and sliding surfaces. Gently sand edges of components if they are too tight. |
| Password dial does not align correctly or lock does not engage. | Incorrect assembly of internal locking mechanism; password miscalculation. | Carefully re-check the assembly steps related to the password mechanism in the instruction manual. Ensure the password was recorded accurately during setup. |
| Pieces break during assembly. | Excessive force applied; thin or delicate pieces. | Handle delicate pieces with care. The kit often includes spare parts for common breakage points. If not, contact customer support. |
