The seller didn't add a clear description on the outside of the package, and because of that Customs didn't allow to be delivered and sent it back. You need to add a CLEAR DESCRIPTION of what is inside the package such as "Plastic Model Kit" otherwise Customs will not let the package enter in the country

I had a fantastic experience with Plastic Model Republic! My order arrived quickly and in perfect condition, thanks to their careful packaging. The model kit is high-quality and exactly as described. Their vast selection and great customer service make finding rare Japanese kits easy. Highly recommended—I’ll definitely be shopping here again!
