I needed a 'freezer' container to transport my Cream Cakes to my local market - I found just the thing with JBP 20Kg Standard Deluxe Box. With the Freezer blocks I also bought this was an excellent choice. I would highly commend this product - it did what I wanted and kept my cakes cool through out the day (within the 5 degree and lower that is required by the Food laws in the UK) Well done JBP for the help and advice you gave me on which box to have.
