What is the safest way to ship a model?

Wrap the model in soft tissue, then surround with bubble wrap. Place in a snug inner box, then put that box inside a larger outer box with foam peanuts or crumpled paper between them. This double-box method absorbs shocks from any direction.

What is volumetric weight?

Couriers charge by whichever is greater: actual weight or volumetric weight. Volumetric weight is calculated as Length x Width x Height (cm) / 5000. Large lightweight packages often cost more due to volumetric weight.

Should I remove fragile parts before shipping?

Yes. Remove aerials, antennae, gun barrels and any other thin or protruding parts. Wrap them separately and include them in the box. This significantly reduces damage risk during transit.

Which UK couriers are best for models?

Royal Mail Special Delivery offers compensation up to £500. Parcelforce is reliable for larger items. Avoid economy services without tracking. Always insure for the full replacement value, not just the kit cost.

How We Calculate This

Calculates the box size needed based on model dimensions and required packing thickness, plus weight estimates for shipping.

Formula

Padding = Base packing thickness x Fragility factor
Box dimensions = Model dimensions + (2 x Padding)
Volumetric weight (g) = (L cm x W cm x H cm / 5000) x 1000
Chargeable weight = Greater of actual or volumetric weight
