Shipping would depend on exactly how much a fully packed envelope or box ends up weighing. If my calculations are correct, though, each ball only weighs a little more than half an ounce, so unless the box/envelope weighs more than .4 oz (and the USPS doesn't up their prices) it shouldn't be more than $1.22 + cost of the packaging to ship within the US. (Unlike some places, I won't overcharge for S&H.) International…will have to be dealt with individually, although a quick glance tells me it won't be too much more than that.

For an estimate for right now, just assume between $2 and $2.50 for the full S&H price, though it should be less than that for a single Pokéball. If you order more, though, I'll find out exactly how much it'll be, but you can at least get the shipping cost (not the packaging) here. Just add about 75˘ to $1 for packaging for now; I'll find the actual amount when I get enough interest.

Also, I've finished painting another couple types of balls:

If you don't know, it's the Premier Ball and the Great Ball. Let me tell you, I constantly over-calculated how much clay I needed for the tabs on the top. Still put too much on one of the tabs. Oh well, that gives it individuality! And uniqueness!

I should have some Ultra Balls in my next picture, just didn't get to them tonight. I still have 5 balls to paint, and two of them shall be Ultra.
