...unless you want little wads of yarn roving floating in your fish tank or terrarium. I received a little cup of small, damp, grayish-green balls, but being new to marimos I didn't really know what to look for. Over the course of a week or so in the tank they slowly became more pale and gray as if the color was fading out of it like a dye, and I did a bit of research and realized I'd been swindled. I dissected one and I'm fairly certain it wasn't even any sort of living plant matter, it seriously just looked like a balled up piece of synthetic fibers. They went in the trash and I found some actual lush, green marimos.

Ex Output:
negative

We’ve had ours for a little around a month and the black strip that is holding the top to the base is fraying and breaking. Other than that it does keep everything cold for a long time! Update.. the underside of the top completely busted this didn’t last long at all 😡
