I always stuff them in a plastic baggie when I ship them because I don't know a better way to keep them tidy.
I came up with this HolyOak Cracker Keeper that is doing a great job. Its just a flexible key ring with a "Holy Oak" attached but I think it adds a bit of class to my crackers.
I know I like having my crackers together and organized instead of getting loose in the bottom of my whip bag.
No, they aren't for sale out right. If you order a whip you will get one.
