Gray w/ White Cap only as far as I can see. Select the appropriate option from the drop down menu.
I don't know what you're going to do with 4 of them or how you might plan on getting to the $49 spend on Prime International orders to get the free shipping (Maybe the recent cast iron skillet deal) - But if you have the means to meet both then it's a pretty good deal.
I'm a fan of these bottles. Long lasting, hard to break and very simple design. There's not much that can go wrong with them.
Best next price I could find was $16.90 for 1 at Tentworld. Which is also a reasonable price in its own right.
