I have been hunting for thermal carriers with gel packs in the base to carry my high

3 layer cakes with cream cheese frosting nice and fresh to destinations without refrigerator space..

Does anyone have any ideas? I found one short one on amazon, but not at a height which will

carry my large cakes cleanly, and an internet search found one at amazon uk, (Viners thermal cake carrier) but they don't ship to the usa.

Thanks.

Can you buy a CakeSafe and somehow add in your own ice packs?
