Hi,
I've done some purchasing of bowling balls from both here and ebay, and they have almost always come double boxed. But the outer box is usually not a bowling specific box, and seems to be a hair bigger than a regular bowling ball box, allowing the regular box to slip inside easily, but snugly. Where do you get these boxes? I'm looking to start selling some used equipment, but most of my boxes are a bit beat up from multiple apartment moves...
