The layers series is a fun, playful design inspired by layers found everywhere in nature. from the layers formed in stone to the layers in onions. The stacked layers come from rest streams, leftovers and locally sourced woods. The grinders are available in 3 different sizes. They feature an excellent design that will stand out in your kitchen and dining table. Go for intricate detail, or choose the XL grinder to make a statement. The wooden mill will season your meal perfectly for decades with a minimalist style. To fill the grinder, pull off the top and push the lid back after you fill it with spices, Salt or pepper. Setting the coarseness is done by turning the grey knob on the bottom clockwise for a finer grind and counterclockwise for a coarser grind. This system is easy to use, efficient and very durable. The internal mechanism is from crushgrind (in our opinion, the best in the field ;) and has a 25-year warranty on parts). In addition, the porcelain drive allows the Salt to be crushed without the risk of corrosion. Note: The Grain of the wood and the layers will differ from the pictures. Each Grinder is Unique and Different since they reflect how the tree has grown.
