Rosineer 2.5" x 2.5" Square Pre-Press Mold, Anodized Aluminum

How do you use these pieces?

Assemble the pre-press by stacking the pieces. The short piece without the logo is the base; the hollow one serves as the chamber walls; the one with the logo is the lid that goes on top of the hollow part.
You fill it with flower of your choice or pollen, or you can fill your filter bag first and insert it in the pre-press. Place the lid (the piece with the logo) on top and use your hands and body weight or any press to apply pressure. The purpose is to remove air pockets and make your material of equal thickness.
