The Grinder Deluxe is an all-in-one item with multiple layers. Lift up the magnetic lid to reveal a grinder in the first layer. Unscrew the grinder to reveal a strainer in the next layer and underneath is a storage compartment on the bottom. This item is secure so no need to worry about losing your contents. Like our other grinders and smoking accessories, it is made of aluminum alloy with an anodized surface finish. There is a nice imprint area on top for your brand!
