We use reinforced cardboard boxes specifically designed for international shipping to protect your packages from damage.
We double-package the original packaging from the outside and add additional cushioning materials as needed.
Therefore, the weight may increase after packing due to the materials used.
If you prefer to reduce the weight and size of your package, you may consider using Reduce Packaging Service.
Reference: I don't need cushioning materials, so I want to reduce the weight/size of the package during packing.
