Porlex is a Japanese company that specialises in ceramic food grinders/graters. The silicon band gives a firm grip around the cylinder while grinding. The handle can be stored alongside your grinder when not in use. The grinder’s inner spring helps maintain the grind consistency especially for a coarser grind size. The stainless steel body makes the lower compartment which holds the ground coffee static-free. The ceramic conical burrs are easy to clean and durable. Being a perfect size for carrying with you on your travels, it is also a bonus knowing that it fits nicely in an aeropress!
