The Space Case pollen press is composed of five pieces. The pollen press is 1" wide and 2.5" tall, and comes with two Teflon coated plastic dowels in addition to the caps and main body of the press. The metal peices are made from aerospace grade aluminum, making them lightweight and durable. Polished to a shine and complete with a grip on the caps so they're easy to screw on and compress with. The Space Case pollen press is precision machined, so the pieces fit together perfectly and turn smoothly. Collect the pollen from the bottom of your Space Case four piece grinder, and put it in your pollen press after taking out one of the dowels. Replace the dowel and put the cap back on. Screw the pollen press together as tightly as you can. Reapply pressure every two hours for best results. Compress the product for a minimum of eight hours for best results. The Teflon coating on the dowel will keep the pollen from sticking. Due to high quality of the materials used to make Space Case brand tools, this pollen press will last and create consistently good results. Dimensions: 1" wide, 2.5" tall. Precision machined from high quality aerospace grade aluminum.
