The TetraFauna ReptoFilter Filter Cartridges come in a lot of 4 boxes. One pack of filters was opened and only has 2 filters in the box. You are buying 11 filters in total. Some of the boxes got wet/damp but all the filters were safe and stayed clean and dry. I wouldn't sell something that I wouldn't use for my lizards. I switched water sources and don't need these size filters anymore. Thanks for looking!
