Crumbcake, if you have ANY concerns whatsoever, just contact Scott or Juli at www.cakesafe.com
and they will answer any questions you may have. I talked to them a lot when I first got mine, they really are top notch folks who care about their products. (and BTW, I no longer center dowel my cakes that are delivered in the cake safe - the rod goes right through the foam core I use - which is 1/4" and 1/2" - the system is foolproof!) You'll love it and not know how you did deliveries without it once you use it!
