This does make storing a cake much easier.  The seal around the bottom of the lid creates a good seal and cakes does last a few day - if the kids leave it alone!  Colour is retro and fits into most colour schemes.  For a normal size cake (20cm) tins, it fits well and there is a good hight to the lid so even those rather taller cakes seem to fit in without the icing sticking to the lid.  I am very happy with this product and would recommend it.
