Herb and Pollen Light Duty Press - 5pc, Large, Silver. This Revolutionary tool will transform the way you press material! An add-on to the grinder, this product is used to press your pollen, forming a hard extract that is so pure.

Once in the press, place the removed pin back in the press and screw the lid closed. For best results, let sit overnight allowing pollen to fuse together and form a hard extract. Remove from the pollen press and enjoy! Sharpstone is known for manufacturing the highest quality grinders and accessories.
