Hello, I tried to mail my friend Kyruya 50 pokeballs I had bought for him. When I tried to send the mail, (name spelled right and everything)It gave me a message saying, "Your items could not be sent." I tried it again 5 different times in a timespan of 15 minutes. Nobody seems to know what to do but told me I should post it here. Is there anything I did wrong and can do?
