I didn't know but they showed up in a nice little zippered storage bag to keep them together when your not using them. They have little silicone tip covers on the ends to keep the "sharp" ends protected from damaging anything. They extend really far out, I actually think they extend a little too far because if fully extended, they feel flimsy and I don't like that. As long as they're not completely extended, they feel nice and sturdy and work great for both marshmallows and hotdogs!
