If you were local I'd give you half a dozen. The best for protection, high slosh factor though they're noisy.
I've only bought pulp ones, but have received them and sent them back. They're for 750's usually, though make sure you pack bottles in there tight. You might need to put padding under the bottle, around the sides, and even around the neck (especially true for bombers and smaller bottles). Some shippers can handle two cans per slot, some need slight modification to do so. Lastly, check all sides of the box to make sure it doesn't say bottle/wine shipper on it! It takes 20 seconds to cover well and if a shipping employee sees it, your box might get exception'd.
I get mine from all the wine I order from wineries. I am in their clubs, so shipping is cheap or free. I take advantage of free offers from them, and then purposely order the amount I need for the shipper size I need. My problem as of late is I've ordered too many cases and those boxes are damn big! @Hopasouras you'll see that big arse box I just sent you! lol
