We recommend sending parcels as regular parcels instead of small parcels. Usually small parcels are not insured and longer delivery terms apply. Make sure to pack the unit carefully as it is a sensitive electronics component that is very susceptible to damage. We also recommend using a carton that is larger than the component (5 cm extra space on each side), wrap the component in bubble wrap and fill the remaining space with packaging materials (e.g. polystyrene chips).
