This has got to be my favourite product of 2011 so far. The Ped-egg has got to be one of those items, where you wonder why no-one thought of it sooner. Essentially, it is like a cheese grater for the hard skin on your feet (perhaps, thinking of it in those terms contributed to it not being created sooner). It is easy to use, painless, quick and easy to clean. there are 4 elements to the Ped-egg; the rounded top, the grater (which slots into the lid), the bottom half and an exfoliating piece of sandpapery stuff (attaches to the bottom half).
All you need to do is rub the grater over the hard skin to remove it, exfoliate and dump the contents of the lid in the bin.
