Has anyone here returned a knife to JNS through USPS? Maksim said it will be fine, but Denmark does not allow knives to enter the country that are longer than 4 inches. I returned a sujihiki. He said as long as his company name and Cv nunber or some special number was there, it would be fine, so I made sure to include all of that. I did USPS because Maksim said it would be fine and FedEx was $170 compared to the $60. Just looking for some reassurance. Currently in Copenhagen being held in customs for the past 24 hours. Thanks!
