Great value

I bought a couple packs of this for my Palladium build. It works perfect as a drainage layer and to fill dead space. I would buy this product again.

very handy filter.

I'm using this item for a filtered pet water bowl. I can get about 162 filters once I cut them up into little squares. sure beats by in the package ones of just 12 pieces. the item realize vacuum packed and it's real cool too reinflate with hot water. ready to go anybody an hour.
