6-Pack, Size B, Rite-Size Cartridge Refills

Yes they did

Love the filters

Just like the original one. Does what its required

They fit in the fish tank

Works great

Works well

Muy buena calidad y pronta entrega

great colors and clear water

Its the wrong size! It says size B but its actually size C. I have a filter that uses size C so its not a big deal but it should be what the product says.

These are all standard products function as expected
