Dear Customer
*
We are truly sorry to keep you waiting so long.
*
Actually, we found a distributor in the beginning of*last week, however it took us more time *to choose a*good retailer.
*
Finally,*we've found a*good one which is Bigbadtoystore.
www.bigbadtoystore.com
*
BBTS is our official retailer in the US and they will soon contact you directly with information and instruction about our item.
*
They also know well about your name engraving on the plate, however you can tell them again, just in case.
*
As you may know, we didn't charge any money at all.
*
When you get the contact from BBTS, you can make payment on their site.
*
Please let us know if there is any problem with them.
*
I appreciate your patience*and also apologize for the delay again.
*
Have a nice weekend!
*
Thanks and best regards.
