The 4 piece design makes grinding, storage and sifting convenient in one design. The new style Space Case grinder/sifters have the trademark name and "Made in the USA" on the top of the grinder.
Each Space Case comes with a precision machined triangle collector to scrape the pollen from the bottom. The triangle can also be stored in the mid section as well to assist in the separation of the pollen. The triangle is specifically designed to fit the edge perfectly.
