High-quality nylon rosin bag used to separate plant material rosin during pressing

Depending on the plant material used and its condition (full plant, ground up, hash, kief etc.) you would choose a suitable micron bag.

Generally the higher the micron size, the bigger the yield with lower quality. The lower the micron, the smaller the yield with higher quality.
