On April 7, 2026, we packed and shipped a small Yukimi Stone Lantern from Japan to a repeat buyer in the United States via UPS on the same day. The parcel was handed over for pickup within a few hours of purchase, and the estimated transit time was about three days. This page documents the exact packing process we used and explains how we prepare heavy stone products for safer international shipping.
Stone is durable, but it is not unbreakable. Most damage happens when the contents shift inside the box or when impact is concentrated on a corner or one specific point. That is why our priority is not simply “more cushioning,” but a packing method that prevents movement inside the box.

Packing Materials Used for This Shipment
| Material | Purpose |
|---|---|
| Newspaper | Used as the first protective layer to reduce surface friction and minor contact damage |
| Bubble wrap | Absorbs shock and helps spread impact away from corners and raised areas |
| Corrugated cardboard roll | Adds rigidity and helps prevent movement during transit |
| Inner box | Provides the first layer of containment and keeps each part stable |
| Outer box | Creates a second protective shell against drops and compression |
| Hot glue | Reinforces the box bottoms to reduce sagging and bottom failure under weight |
| Stretch wrap | Adds final reinforcement and helps stabilize the finished package |
Packing Record
1) First layer: paper wrapping
Initial paper wrapping

This first layer protects the stone surface and reduces fine abrasion before thicker protective materials are added.
We begin by wrapping each stone part in paper. It is a simple step, but an important one. It reduces surface friction and helps keep the stone from rubbing directly against bubble wrap or cardboard in the next stages.
2) Bubble wrap for shock absorption
Each part wrapped in bubble wrap
Heavily protected parts
Extra protection on corners and edges
Corners, edges, and raised sections are more likely to take impact during transit, so they receive extra protection.
Next, we wrap each part in multiple layers of bubble wrap. With stone products, special attention has to be paid to corners, edges, and any raised section where force can concentrate if the parcel is dropped or compressed.
3) Placing the parts into the inner box

Parts stabilized inside the inner box
Once protected, the parts are placed into a properly sized inner box. We keep empty space to a minimum and reinforce the bottom with hot glue. For heavy items, the strength of the base is just as important as the side walls. If the bottom weakens, the entire package becomes unstable.
4) Double-boxing with an outer box

Completed double-box protection
After the inner box is secured, it is placed into an outer box for double-box protection. This structure adds another layer of defense against drops, pressure, and corner impact. The bottom of the outer box is also reinforced with hot glue so the weight is supported from underneath, not just from the sides.
5) Final reinforcement with stretch wrap

We then wrap the cardboard box multiple times from three directions with stretch wrap. This strengthens the package itself and helps it withstand external impact more effectively.
6) Final inspection and same-day shipment
Final condition before UPS pickup
Before shipping, we check the rigidity of the box, the balance of the package, and the strength of the seal.
Finally, we inspect the finished package for rigidity, sealing quality, and internal stability. This order was shipped by UPS on the same day. We do not skip steps just to move faster. That consistency is one of the reasons heavy stone products can be shipped internationally with lower risk.
Why This Packing Method Matters
Stone usually does not fail because it is weak. It fails when force is concentrated in the wrong place. That is why our method focuses on three things: surface protection, structural rigidity, and no movement inside the box. This shipment to the United States is a practical example of how we apply that principle in real work.
FAQ
| Do you use this packing method for every order? | Yes. This is our standard approach for international shipments of heavy stone products. |
| Why do you reinforce the bottom of the box with hot glue? | Because heavy products put significant stress on the base of the box. Reinforcement helps reduce the risk of sagging or bottom failure. |
| Why do you use a double-box system? | It adds a second protective shell and helps reduce damage from drops, pressure, and corner impact. |
| Can any packing method guarantee zero damage? | No. But reducing internal movement and spreading out impact greatly lowers the most common causes of chips and cracks. |
