No problem!
I'm not sure how you'd prevent phasing during shipping... It would depend what climates the balls are going through when shipped, the length of time the ball is in a UPS/FedEx facility waiting to get on the truck, the length of time it's on the truck waiting to be delivered, if it sits outside your house when it's delivered, etc.
If you ordered in the spring/summer/fall, where temps are pretty warm throughout the US, I'm guessing you'd have a better chance of balls not phasing on you when being shipped.
