We do have different types of grinders and they are ALL refillable! We really care about our environment and like to minimize the 'garbage' we have with disposable grinders. Grinders have two parts: the bottle and a grinder top. We have two types of bottles, glass and PET (high gloss transparent plastic). The grinder tops are specially designed for sea salt and black pepper in the colors white or acrylic for the salt and black or acrylic for the pepper.
