Disposable pepper grinders are great. They are incredibly efficient int the way they are built, they do (surprisingly) not actually use a lot of materials and might therefore be even more economical than a “Real” peppergrinder for most non-professional household users and, often, they do not look terrible. Most importantly, though, they are simple and they understand how people use kitchens and pepper in particular. One does not want to have a separate grinding device and pepper, but a simple integrated solution that allows to grind pepper, on demand, without taking a lot of space, or requiring any maintenance, ever.
