It is important to note that all Marimo sold from Aquatic Arts is responsibly collected and put through a rigorous quarantine process to ensure safety and quality. All of our incoming Marimo shipments are inspected and cleared by DFW/USDA before we receive them. Upon arrival, we quarantine and treat all of the Marimo for a minimum of two weeks, to fully eradicate any pests, including zebra mussels. This includes a saltwater bath that kills any “hitchhikers” that may be attached without causing any harm to the plant.
We take conservation very seriously here at Aquatic Arts, and we go through great lengths to support it. It’s in everyone's best interest to remain vigilant regarding invasive species. Because of the lengthy, tedious, and strict quarantine process that we follow, it is impossible for invaders of any kind to survive. As far as we know, we’re currently the only Marimo supplier doing anything like this, and that definitely sets us far apart from the rest.
In observance of state to state regulations for containing any potential spread of an invasive species, temporary restrictions have been implemented by the following states. Marimo orders from these states will not be sold or shipped at this time:
Alaska
Arizona
California
Hawaii
North Dakota
Oregon
Pennsylvania

Marimo Moss Balls are one of the most popular plants in the aquarium hobby. In Japan, they are widely kept as ornamental plants in jars. These moss balls can be quite useful for the aquarium because they generate oxygen and remove nitrates, improving water quality. Marimo are often sold in the form of "nano" moss balls, which are much smaller. Our giant Marimo balls will be 1-1.5 or more inches in diameter. If you wish, you can cut the moss balls into smaller pieces and the individual pieces will grow into separate nano Marimo moss balls.
The lakes in which Marimo are naturally found are cold in temperature, so Marimo do best in cooler water (we recommend a water temperature no higher than 76° F). Brown spots may form on your Marimo if their water is too warm. If you find your water gets too warm during the hotter months, you can give your Marimo a “vacation” by putting it in a water-filled container in your refrigerator for up to 24 hours at a time.
Marimo balls are regarded as good luck charms in Japan, and since they have been known to live to 200 years and beyond, they are often kept as family heirlooms. They are thought to symbolize close bonds between family members or close-knit friends, and are often passed down to children and grandchildren or nieces and nephews. By the time future generations receive the Marimo balls, they will be larger in size and will continue to grow with each generation. Additionally, Marimo balls are sometimes given to young children as "pets," since the only care they require is occasional water changes.
Marimo balls are also though to represent everlasting love; thus, they are often used as wedding table ornaments or even gifted at weddings. They are appropriate as a gift to the bride and groom, and smaller Marimo balls make wonderful take-home gifts for the guests that can serve as mementos of the newly-weds' special day.

Indeed it is cool!
Color: Grey, Size: King (102" X 90")
I was amazed at how cool this comforter is. It definitely provides a surface that keeps your body cool. One thing to be aware of is that it is very "slippery" and tends to move around on the bed if not tucked in somewhere.

Hotel quality, budget friendly
Size: King, Style: Light
I’ve only used this for several nights. Overall I’m pretty happy with it, especially for the price. It is soft to the touch and has a nice, smooth feel. It’s lightweight but still provides enough warmth for mild to cool nights. I don’t like feeling weighed down when I sleep, so the light fill is actually a big plus for me. If you’re someone who sleeps hot, this is a solid choice. The corner tabs are super helpful. I paired it with a duvet cover and haven’t had issues with shifting or bunching. It also fits my bed well, though I could see it being a bit short on the sides if you have a very thick mattress. This is a great budget-friendly option and seems like it will be easy to maintain.

Great Value but not for Hot Climates
Size: King, Style: All-Season
This is a fantastic, fluffy, thick duvet for the price. I really like it. Only issue is that it is definitely warm. I live in an area with hot summers, and we keep the AC around 73-74 overnight and this is way too hot for that. I had to replace it with something thinner. I love the feel of this duvet inside of my cover, it feels super nice, warm and cozy. It is just too hot.
I will try it over the winter months, but it might just become a mat under my sheets to make the bed cozier.
If you live somewhere with hot summers, this won't be the one for you for the hot months. It will be great for someone up north, or anywhere with mild evenings. Wish I could use it. Feels so cozy.

Feels luxury, I approve
Size: King, Style: Warm
I have purchased high end comforters/duvet inserts and this one is somehow my favorite. It's so thick and fluffy.
I was going to do the double duvet insert method to create an extra lush bed situation, but honestly it's not needed at all with this comforter! It poofs up wonderfully inside my duvet cover (king duvet, king insert) and it's like heaven. It's very cozy yet airy, and it moves well during the night and does not fee too heavy despite its weight.
This thing is definitely on the warm end and probably won't be suitable for Florida summers, but depending on how you set the AC at night it could be fine!
The comforter is weighty, it feels like quality, and has a soft fabric. I wouldn't use it without a duvet cover, that's more of an aesthetic choice but I like keeping it clean. The white is very white.
Honestly, I will be getting another one simply because I'm so impressed. Definitely no need to drop $300+ dollars elsewhere.

Great duvet insert
Size: King, Style: Light
Perfect duvet insert. I got a pretty expensive duvet to cover this and they worked great together. The fit was perfect and I didn’t feel like the duvet was smaller than its cover. This was a cheap option that keep us warm while not being too think. This product is also breathable and recommend if you live in a place that transitions from hot to cold often.
