All of our finished products are guaranteed for one year.
If non-artificial damage we will mail you a new one.
If it is artificially damaged, you can mail it to us for repair (you are responsible for the round-trip freight), or you can choose to pay a certain fee for a new one.

For non-finished products (such as some kits or parts), please check the quality of the goods immediately after receiving the goods. If there is any problem, we will re-post.
