Congradulations, you beat the bad guys!!! I reccomend that everyone go out and try this and then give us a full report on the outcome.
Yes, you may have gotten these items through customs, that is possible. However, what you did is still illegal even though they let you through.
The customs officer could have unaware of the guidlines of the importing of these replicas or just simply didn't care. In short, you got lucky, they could have very easily been taken from you along with a lengthy search of your vehicle and bowels, not to mention being backlisted making it an unpleasant experience to travel outside of the country.
Please don't promote yourself saying 'hey if I can do it, you can do it" The last thing this sport needs is more restrictions.
