Would you buy this product?

This looks like a hard plastic condom that would be rather uncomfortable. I would not buy this product myself. Take it I do not eat a lot of fruit anyway, but if I am going to carry food or fruit to eat later on I would more than likely want to carry it in some sort of lunch pale.
