I purchase these cases (8 x 5.5 inch black version) to store biomedia and charcoal in my Penn Plax Cascade 1500. They work great and are perfect for the tray in my canister filter. They have a zipper that allows the bag to be reused. The pore size of the filter bag is quite large, so they are not suitable for Seachem purigen, but the ultra-thin version can do. Will definitely buy again in the future.
