A FEW SMALL QUESTIONS

Small, round, full of surprises.

Getting to know your new little roommate.

Wait, what exactly is a moss ball?

Marimo are freshwater green algae that can form a rounded shape. They’re called moss balls, but they aren’t actually moss. Small, soft and wonderfully green.

Do I need a green thumb?

Start with clean, cool water and indirect light. Your moss balls will come with care instructions to help you find a simple routine. They are living things, so a little regular attention matters.

Can I put together my own terrarium?

That’s the fun part. Explore the builder to choose your moss balls, glass vessel and stones. Your summary shows each selected component before you add a complete kit to your bag.

How do I choose the right size?

Check the dimensions on each product before choosing your vessel. Leave room around the moss balls and keep them submerged. Exact sizes and quantities will be listed with the collection.

Would this make a good gift?

A tiny world is a lovely way to say “I saw this and thought of you.” Choose a style that suits their space, and make sure they have the care instructions too.
