Rosin Evolution bags are designed to withstand heat and pressure. Each bag will hold 10-15g and is turned inside out for maximum yield. For best results, aim for 1000-1500psi and limit each bag to 15g of material. The bags will not melt until about 430F/220C, but we recommend 180-240F (82-115C).

The 25 micron bag is the best choice for dry sift, bubble, or other concentrates. This bag also has a custom seam specially designed to contain the fine particles and prevent blowouts.
