Question: ...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.

Answer: negative

Question: This bedding set is better then I hoped. In the pictures the pattern on the sheets looks like a gray color. In reality it's a lovely purple like the flowers on the comforter. Nothing shrank when we washed it. It all came out perfect. My daughter loves it.

positive
