Rosin Evolution bags are designed to withstand heat and pressure. Each bag will hold 30-40g and is turned inside out for maximum yield. For best results, aim for 1000-1500psi and limit each bag to 40g of material. The bags will not melt until about 430F/220C, but we recommend 180-240F (82-115C).

The 37 micron bag also has a custom seam specially designed to contain fine particles and prevent blowouts.
